That is not quite true. You might think it's not "indisputable" however there is evidence that corroborates many of the Biblical accounts as studied by academics and scholars [0]. Much of this is archeological, statistical, along with a significant amount sociological support as well. There is generally still some level of "faith" involved in religious beliefs (obviously), however it does not mean that those that hold them hold no scientific evidence at all.

It's possible that you have researched for yourself and have some evidence for your "beliefs" presented by your statement. Many people (admittedly on both sides of the fence) have not done much research in this regard, but in my opinion is a valuable exercise, so if you haven't I'd highly suggest it.

[0] The Case for Christ (Lee Strobel), along with The Case for Faith and the Case for a Creator. He was a former atheist who initially set out to prove God did not exist after his wife converted. This is certainly not an extensive list of resources out there, these are just some that I remember off the top of my head.
