One of the first things I came across that began my path towards doubt was the population problem of the exodus. The Torah tells us that 600,000 fighting men left Egypt during the exodus, which would amount to about 2 to 3 million people in total. What is the problem with this scenario? Egypt at the time only had about 2 - 3 million people in total! This would have meant that all of Egypt was practically gone at the time of the exodus, yet with all of the well documented history we have from Egypt and the surrounding nations at that time, not one thing mentions this, nor does it indicate that anything changed at all.
But it gets even better, apparently our tradition tells us that it was only 1/5, others say 1/50 and others say 1/500 of the Israelites left Egypt. So conservatively using the 2 million estimation that right before the exodus there were 10,000,000 or 100,000,000 or even 1,000,000,000 Israelites living in Egypt. Now if that isn't totally absurd I don't know what is.
Has any Jewish scholar addressed this issue? Do frum Jews simply blind themselves to this glaring problem? I know that I did for a long time, before I finally came to terms with its implications.
