OP, IMO you've discovered the Achilles' Heel of all faith-based religions. They're all based on ... blind faith ... 1. that events - which you're required to believe in - truly happened the way they were recorded, 2. that associated doctrines - which you're also required to believe in - were correctly interpreted, correctly translated, correctly preserved, etc., 3.. that intermediaries (saviors, prophets, priests, etc.) - whom you're required to believe in - truly existed and truly taught those doctrines, and 4. that historians, archaeologists, etc. who reconstructs this history - individuals whom you must also believe in, consequently - also accurately interpreted their data.
After realizing this truth for myself - that little to none of the above was personally verifable - I had nothing more to do with faith-based religions.
