The pyramids and the Great sphynx at Giza were built around 2575-2150 BCE according to many egyptologists. They claim they were built by the Egyptians. Here's what I don't get about the timeline. The Pyramids lined up with the stars on Orion's belt and the sphynx faced the constelation Leo around the 10,500 BCE. It is evident that the sphynx was has damaged cause by water erosion from heavy rains. There weren't heavy rains during the time period the sphynx was supposedly built nor since. There were heavy rains long before.
If the pyramids and sphynx are 12,500 years old that means that advanced civilization existed without a doubt much earlier than many people belive. When I say advanced culture, I mean they knew things about the physical universe that we are only just begining to understand. They had advanced mathematics which means they had some kind of educational system and probably a written language back then as well.
People always say the pyramids were built to be tombs. No, they were not. The pyramids were built long before dynastic egypt and the pharohs. They probably lived in the shadow of the pyramids not knowing what purpose they served the ancients. The Pyramids May have been some kinds of sonic device according to a few people. Regardless of what the pyramids were used for they weren't tombs. The pyramids had giant pumps running through them. Pulse pumps. Water circulated through them. People aren't sure why this is.
Older than the Pryamids the are the structures underneath them. People rarely talk about them. The Pyramids are old but there are structures under them. People have been so convinced that the pharohs built them as tombs.
There aren't just Pyramids in Egypt they are all over the world. They are very old.
