Because it's nonsense. The Chinese characters thing particularly. Some dude in Texas makes an assumption based on wishful thinking and you taken it as gospel(pun intended)?
Nope. I put in the work. Looked up the characters myself.
Not to mention the religious practices of the first dynasties matched the Jewish practices.
Not to mention the migration from the cradle of civilization was a real thing.
Not to mention that the first eleven chapters of the Torah really had been passed down orally from generation to generation for thousands of years.
So it is your belief that is without any factual basis whatsoever.
