Every Bible student knows that Moses wrote the first books of the Bible in the first months after the exile, because in them he wrote down many laws that God gave him directly for the people that He Himself formed from some descendants of Abraham, and who he was protecting.
Any interested Bible student can establish a biblical chronology that shows that Moses led the Israelites out of Egypt in the year 1513 BC.
Of course, there are many Bible haters who do not want to study these matters, but who are very willing to believe what modern Bible haters want them to believe.
PS: Maybe in the future I will create a forum topic about biblical chronology in detail... I have already done it in other forums.
Maybe you don't realize that there are actual theologians here, not just layman. Maybe listen, and learn? Or not,.your choice really.
