You are dumb.
Pyramids were built buy slaves and used as tombs.
Homo sapiens had reached full behavioral modernity 50,000 years ago.
No neanderthals younger than 30,000 years have been found.
There were any number of ways a mammoth could die suddenly all more plausible than a polar shift. It also hasn't been ruled out that some mammoths or just that mammoth had a habit of keeping food in their mouth for later consumption.
Funny how quickly you guys call anyone "dumb"
Pyramids were not necessarily built by "slaves". Plenty of evidence which suggest they weren't just slaves.
Pyramids were not used as tombs. Plenty of evidence which suggests they actually produced electricity.
I'm not posting evidence. Google it if you care
