Re: Wrangel Island
The Old Kingdom Pyramids in Giza at least were built about 2500 BC so 4500 years ago, not 5000.
The Middle Kingdom Pyramids were about 4000 years ago.
They didn't bother with Pyramids in the New Kingdom.
The oldest Egyptian Pyramid was Djoser's at Saqqara and that's still only about 2650 BC and that wasn't really a true pyramid. Really you'd be looking at the Red Pyramid as the first true pyramid.
Anyone for Serious Sam?
