Not to mention the dogon people and sirius b
I believe that human civilization has reached an incredibly high level of sophistication, then has been completely destroyed (by war, natural disasters, etc.), only to be built back up from scratch several different times.
The same way you have advance societies and not advance. You had cultures building Pyramids but you had some who couldn't build a perfect tabernacle to pray to their gods. . Why does it got to be Aliens?
Again, why does it has to be aliens? We just had major climatic rotation axis change 12,000 years were shyt was destroyed and changed forever.
Yeah it does if you study history. They told you how the Stonehedge was made if you read history thousands of years Africans came to Europe to build as told by the people of that area of that time. It is stones that is hedged in the ground the same as Europe in Africa and in the same exact fashion but not as huge.
Shyt the Inca/Mayans/Aztec reported that all their monuments and pyramids were already built when they came to South America and the same is told about Egypt. Human civilization is old on Earth man. Who to say we couldn't fly back then or something else.
So wait. we could fly back then? So what took the Wright brother so long? we talking a couple thousand year gap man. I get it Humans are smart, but THAT smart. CMOM cuz.
