The bible attempts to make the Israelites/Jews look important. They were a bit like the North Koreans of contemporary times, who are always trying to make themselves look powerful.
Why were the Jews doing that? Its because they claimed that their YHWH was the only true god and all the other gods of the nations were nothing. Think of the message in the Elijah and the Baal priests story.
The message behind the exodus story, is that YHWH is so powerful, that the then mightiest nation in that world era, was no match for YHWH's strength and power.
For most past events in 'real' history, there is some corroborating evidence that something happened. There is nothing in 'real' history to corroborate this bit of puffery.
It's all 'piss and wind.' As is the WTS's attempts to prove its true. The WTS's argument is to say that the bible has 'true' history, but the Egyptian record is not true.
Read it for yourself (See the Aid book, pp 540-548).
And, keep thinking about why the OT does not mention that Egypt also ruled Palestine for long periods, with Egyptian armies often supporting their local satrap?
