They revised their history to suit their boasts. The Exodus of which you speak is a colossal revisionist boast.
You failed to rebutt the contents of my post.
Some facts for you to consider: The Hebrew Bible indicates that G-d appeared in front of the entire nation of Israel at Mt. Sinai. No other religion in the entire history of mankind ever made that claim (and, BTW, the Bible specifically indicates that no other religion ever will make that claim). It also mentions, dozens of times, the Exodus which "you" (meaning the Jewish people) witnessed. The Bible also very forcefully mentions that not one single letter may be added or subtracted from its text.
In order for the Exodus to be a "colossal revisionist boast" you would have had to create events in the public record of the Jewish people that didn't occur - in the face of the entire nation having witnessed the event. It would be like saying that George Washington never existed. You literally cannot make that up - it would amount to a vast conspiracy, the likes of which has never been heard of before in history. Not just the 2 million, but also their descendants for many generations would have had to have said nothing when officials and religious leaders lied in public. If you heard something totally fantastic about what happened to your nation several decades before, wouldn't you say "Hey, my father and grandfather never told me about that"? If it was several centuries later, a similar question would arise for those who were adults upon the introduction of the new information - "how come we never heard this before?" If it was based on a new book of the Bible that was found, wouldn't the person who found it be discussed/memorialized somewhere in Jewish literature?
To deny outright that which you don't believe, without analyzing the logic or the facts presented by those who do believe that thing is, itself, a highly illogical and unreasoning stance.
