Did the collapse of D₁₂ enable the Hyksos rise to power?

Assume the “typical lifespan” of a Hebrew person at that time was approximately 60 years. This would imply that four generations of Hebrews lived in the land of Goshen during the twelfth dynasty. This agrees with scripture (Genesis 15:16) which says; “But they will return here in the fourth generation”.

I think you say the dynasty lasts 225 years.
That's arguably about 10 generations.
Most of us don't leave it until we are 60 before begetting the next generation.

Yes, but the scriptures also say they lived for 969 years in some cases not sixty, believe it or not the argument doesnt stand.

It appears that some impressive stone carvings and statues from the 12th dynasty were re-worked and re-used in later times. They may have served later pharaohs as religious-political propaganda.

This speaks to the impressive grandeur of the 12th dynasty. Its end was sudden. Please see attachment.

In many science fora it is popular to dismiss Biblical references. It is also popular to opine Christianity as a Roman invention of Constantine for political purposes. I would caution that lack of evidence as to the historicity of Christ is not evidence of His non existence. I do agree that the Christian Bible is not a factual history. However, the Torah and the New Testament do offer information (of belief systems) that I accept as approximations of actual events. It's best for scientist, especially, to keep an open mind as to what is proven and what is surmised. How many stories were retold and repeated and embellished before they were recorded in written form? The older the more valuable the insight into past human social order.

… just lots and lots of fairytales like abraham amd methusela, noah and his ark, who all lived for hundreds  and hundreds of years.

“One thousand years in your sight are but a single day…… .”  (International Standard Version)

God’s years are not quite the same as ours. Leads to confusion, sometimes!

More seriously; I understand there is a theory that Moses got the idea of a single God from Akhenaten.
That’s before you get into the idea that Moses and Akhenaten might have been the same person.   

Yeah, I once heard of that theory. To be perfectly honest, I don't think there is much ground to that. Atenism was a religion that was clearly based on the worshipping of the sun, a concept the Old Testament clearly rejects.
But the more convincing argument against this theory might be the relative late rise of monotheism in Canaan. Up the 8th-century BC it seems like some sort of polytheism still have been very widespred there, the Bible actually mentions this pretty explicitly. Some historians like William G. Dever even argue that ealy Judaism wasn't monotheistic either having some kind of pantheom including Jehova, Ashera and their son Baal, but that's highly disputed(no wonder, considering it's about the history of one of the oldest still practicized religions). Just google the book: "Did God Have a Wife?"
