Just felt the urge to jump in here.
I have actually been to Egypt and entered one of the Giza Pyramids, and various other sites (Karnak, Edfu, etc). Been to the Step Pyramid (Pyramid of Djoser built about 2660 BC) as well. The Great Pyramid if Giza was built around 2560BC.
I mention this, because some JW's seem to think that there could be some mistake about the dates of various reigns of pharaohs, or when things were built. If you have been there and looked around, you would realize that that is virtually impossible.
There is writing in stone, everywhere. There is so much written historical narrative, and so much overlapping in that historical narrative, that sequencing events becomes unarguable. Also the ancient Egyptian numbers are easy to understand (a bit like Roman numerals) and as an agrarian society (and because of annual Nile flooding) they were clearly aware of when years start.
As a result, there is a mostly continuous list of pharaohs going back to around 3100 BC.
In 2370 BC, the supposed year of the flood, Pharaoh Unas of the Fifth Dynasty was on the throne for 5 years, and was to remain there for a further 25 years. His pyramid is not very famous (there are lots of them), is in bad condition, but is still there and was around 45 metres high. His successor (first of the 6th Dynasty) also had a pyramid, as did the rest of the Sixth Dynasty pharaohs (unless they had a short reign). There was continuous building work going on from before the date of the flood, to 2181 BC at least.
Fisherman, you are a smart person, probably smarter than any member of the Governing Body. You shouldn't just be parroting the lines from Brooklyn.
