It is pointless to answer with a particular religion because all of them require an element of faith to get over that threshold of disbelief. There will never be a good answer without major controversy. If I had to pick one that makes the most sense and might actually have some basis, Christianity has the most historical/circumstantial evidence. Many of the places are still in tact today where events happened, or are being excavated. The text of the bible is a historical narrative that is so precise that it has to have some root in truth, when looked at closely. The tombs of biblical figures exist in Israel, and the general Christian story corroborates with secular historical records, but here again it would take a long time to verify this statement, so you can't take my word for it either. Scientists have allegedly discovered that there is a missing day in the solar and lunar calendars coinciding with the day the earth stood still as God's people battled. Judaism is very very close to Christianity, with one key difference, they believe that Christ was merely a rabbi, nothing more. Christians believe he was that, and God too.

The source linked is from a Christian viewpoint, but he does offer a bunch of historical jumping off points (and recent footage) to help continue your search on this topic. Worth a look.

I would have to say that the Church of the Flying Spaghetti Monster, which is a real religion by the way, has the most scientific evidence to back up its claims.

Just look on the official site and see what they have to say.

It is the only religion that is closely connected to science. The Supernoodle theory that is known among its followers is really just a variation of String theory. Also the theory of Gravity and and Spaghetti-Meatball Duality is quite popular even within the scientific circles of non believers!

As a Pastafarian, or follower of FSM myself... I only urge you to check out the tons of evidence that sets this religion miles apart from the other infidels.

Buddhism (a.k.a. the religion of the mind) likely has the most scientific backing as we continue to find more and more research that shows the benefit of meditation, mindfulness and the general mind-training that Buddhism offers.

Buddhism doesn't claim to have a mythical story that needs to be proven - there is only a path to end suffering and the causes of suffering. The "truth" in Buddhism is found by the effort that the individual practitioner partakes in.

There really isn't another religion that you can "prove" as they are all based on faith.

look around you evidence of where we come from is all around you once you shed your nspic (neuro - sematic political illusion complex) we will see the truth in our world it is all around us. nature is where we came from, way before we needed a book of rules and a rent book, nature held us but in our greed, dreams and miss understandings. we formed religion on our own understanding likening our gods to humans to fill the great kazum in our hearts, which serch for meaning and purpose, to feel accepted and special. i dont know the truth but if you look at the religion which has suffered extermination in history, stigma of the devil and even there religious symbols where demonised by the church e.g. the pagan protective pentical or pentagram is dipicted in the christian religion as a sign of the devil. if you take a look at another symbol "the cross" first apeared in pagan religion. as i said i dont know the answer but from my knowlege of life and the way we act, i find us to be entierly natural and down the line we where taken from our belife in nature and the cycle of life. this happened because of those who wished to be rulers of the earth, is it so hard to belive that we are spirits in an eternal loop, living growing dying then returning back to the earth. it takes alot of the romance out of religion but they have one simple rule for those who follow paganism "harm none, do what you will. but now we have christianity and the christian god offers little mercy in this wold of comcrete. so next time you are sat somwhere green why dont you see if you have any of your connection with the earth left, cause pagans dont work the same as christians the had to eradicate them to start the world wide coo.
these are my veiws please feel free to tell me i am wrong, but the amount of evidence is astounding, the flaws in christianity start from the garden of eden where god left a tree to temped them, and what they are saying is we are all dirty bad wrong sinners and we need to repent, misery helpes them keep you payin rent and living in fear of challenging outhority, are we being lied to.......?

I would have to say that there is an inherent problem with what you are asking. Not as others have said that if you have too much evidence for a religion that it becomes a science. (Which is non-sense anyway. Science is nothing more than the verification of facts and processes. If a religion was to be "proved" by science, it doesn't become science. Rather, it becomes scientifically measurable. Very different things.)

But the issue with your question is that you are aiming at the wrong target. Let me begin by example. Lets say that you and I are kids and our mom asks what we were doing out in the yard. You answer by telling her all the facts about the environment we were in and the clothes we're wearing, the length of time we were outside, etc. and then telling her we were playing in the sandbox. But then I tell her we were a small fraction of the information you gave and say we were blowing up GI Joe figurines with firecrackers behind the shed. Assuming I've just told the truth, you'll see the dilemma of what you are asking. More scientifically verifiable facts don't automatically lead to truth.

The better question is what is the core event(s) a religion centers around? For example, Christianity hinges on the death and resurrection of Jesus. If that didn't happen, nothing else matters. But if it did, then no amount of scientific evidence would change the truth of the message of Christianity. At that point we'd have to re-evaluate our assumptions about what the evidence actually means. Because after all, interpretation is a part of science. Hence the reason that rarely is there something considered absolutely true in science. We always know that at some point new understandings can unhinge our previous interpretations of evidence. Quantum physics is a great example of this.

So in conclusion, don't ask what religion has the most evidence, ask the questions what are the central events/truths the religion is based on and what leads us to believe they are true or false? Looking at it now it is mainly just a tweak to what you were asking already. But an important tweak.

christianity and the storys of the bible are flawless, everyone seems to be running from god unstead of to god. Satan is here to deceive us and that is exaclty what he is doing to most of you.. i am astonished that you are turning from the one who called you by the grace of christ, and are turning to a new gospel, which is really no gospel at all.. evedently some people are leading you into confusion and perverting the gospel of christ....with out christ's sacrifice the old testament would be incomplete...gods fingerprint are everywhere open your eyes and see the the undeniable evedence...everyone just wants to believe whatevr feels good... looking for enlightinment unstead of the provider of the light.....love you all, god bless

I strongly suspect most of the facts presented by your Jewish friend weren't really facts. Jews tend to have very scholarly personalities but the more religious depend upon texts rather than science. On the other hand, the Old Testament fares pretty well in comparison to other holy books. From the part about King Solomon on it is mostly a history book, and does reflect real history. But the more religious part, the first few books, do not have facts to back them up. I can't think of any other holy books which even try to relate anything other than philosophy, usually highly incoherent and untestable. Unless you want to count the Scientologists with their space alien fantasies, but that shouldn't count as a real religion. Unless I'm forgetting someone, the Jewish religion wins your question virtually by default.

A close second would be Pastafarianism. The Pastafarian prophet has pointed out the inverse relationship between classical Caribbean pirates and global warming as proof of their beliefs.

Having looked into most of the world's major religions. I would say there is a close race between Christian Science and Yoga beliefs (Yoga as a subset of Hinduism.) While many of the Yogic beliefs about supernatural things are harder to prove or document, the practitioners of Hatha Yoga (the physical study) have passed on a body of knowledge that has frequently been affirmed by modern science and medicine, resulted in physical training such as practiced in many arts & disciplines (dance, calisthenics, herbal medicine, etc.) and as meditation was mentioned, was the original source of the practice even before Buddha was born.

Christian Science makes a compelling case because as part of their practice, they have continuously published reports of medical healing since their founding, an example would be in the appendix to Science and Health by Mary Baker Eddy, their main reference along with the Bible.

That they refer some of the most severe cases of illness to their form of faith healing, have hospices and nurse practitioners trained for this specialty, and keep documented records of miraculous cures, probably represents the most scientifically based of all the faith based religions--their idea of Christian healing put in a logical, scientific framework--it is even in their name. They routinely deal with serious infections and broken bones in this way, and I recall a case of a man with a bullet near his heart receiving positive results.

To an outsider, it would appear that there is some form of hypnotic suggestion combined with the body's natural healing abilities. To the followers they believe they have a logical explanation of God's power to heal people, that this supernatural effect is a form of a rational metaphysics based on the difference of matter and "spirit"--which in physics terms might be another form of universal energy which ultimately is the source of all matter and energy.

I am not a student of religion, but I think that any church that had absolute scientific proof of its validity would have said so by now.

That being said, I believe that Pantheism is the most scientifically provable belief system. Try to find fault in a belief system that claims that everything is made up of energy, good and bad, and that when each thing ceases to exist, that energy is released back into the universal energy to be recycled. It's a truly eco-friendly religion, with no deities, no churches, no political agenda.

It was proved long ago that energy is not infinite, and that every cause has an effect that produces what? Energy. We all use energy for everything we do. Nature uses energy for everything that grows, moves, or lives.

This can all be scientically proven, without doubt. No one can argue with this. Therefore, Pantheism is the only belief system that is almost 100% scientifically valid, no matter what Tom Cruise says.

Wow. wow. I mean... wow. You're combining science and faith as a topic for discussion. Sounds like you should be reviewing the faith of science. Even look into quantum mechanics? Ever ask a physicist if they believe in 'God?'

As already stated, religion is based upon faith. If all the answers were before us in solid scientific evidence faith would no longer be needed. Without the need for faith - where would religion be? Well, it would be a science.

One important thing to keep in mind about science is that even many things that we simply accept as absolutes are still only theories. That force that holds us to the earth; gravity, is a theory. Mind you, it's a pretty convincing one, but it is still a theory.

Being open to possibilities is the start of any theory. I think the same is true within religion - I know a closed mind is an ignorant mind.

I'm fascinated by religion. The different deities belonging to different people and cultures all over the world is a psychology within its own. It truly explains why the majority do and think as they do. And of course, most religions believe that they are the "one true faith" and everyone else is wrong.

When pondering this question I thought seriously about the Buddhist faith. However, as I ran into reincarnation I was at a standstill. There's no possible way to either prove or disprove this just as there's no way to prove the existence of any God(s) or Goddess(es) from any other religion. Superstition is also too heavily involved within this faith.

A Deist follows no rituals, does not dictate to God through prayer, does not expect miracles, does not believe in The Bible as all of these things would be either an expectation or a belief in the supernatural. One example given is people believing Moses parted the Red Sea, Jesus walked on water, someone gave the Mormon golden plates with magical spectacles to decipher it or Mohammed was given the Koran from an angel is dangerous. It leads to a weakened mindset where reasoning is lost and the door opens for people like Jim Jones or David Koresh to manipulate with fear and cult dominance.

Deism has a saying I thought was clever: "God gave us reason, not religion."

Other things I considered weren't really religions, but more categorized as philosophies - Atheism, Agnosticism, etc.

Leaving me with only one other possible answer (in my way of reckoning) - Deism.

Deism is the only religion (to my knowledge) where both faith and reasoning come together is complete and total harmony. One does not overshadow the other and most importantly a Deist's faith is not threatened by this reasoning.

To quote Deist Thomas Payne, "There is a happiness in Deism, when rightly understood, that is not to be found in any other system of religion. All other systems have something in them that either shock our reason, or are repugnant to it, and man, if he thinks at all, must stifle his reason in order to force himself to believe them."

www.deism.com gives the definition of Deism as the recognition of a universal creative force greater than that demonstrated by mankind, supported by personal observation of laws and designs in nature and the universe, perpetuated and validated by the innate ability of human reason coupled with the rejection of claims made by individuals and organized religions of having received special divine revelation.
