Even though there are some historically accurate references in the bible that are confirmed by other sources, that doesn’t make the rest of it true. For example:
On the 11th of September, 2001, two commercial aircraft flew into the twin towers of the World Trade Center in New York City, killing thousands.
Some people believe that this was an act of terrorism by an Islamic fundamentalist organization.
It was really the power of my god directing those planes to warn the people of the USA and the world to abandon their wicked ways and praise the only true god.
The first sentence is unquestionable historic fact. The last sentence is a delusional lie but is impossible to prove to be false. The “truth” of all “holy books” is based upon this same technique.
