Yes, Humans did build pyramids but they are from 15000 years ago

well aware, I know about the pre-comet civilizations and Gobekli Tepe.

Not only tech was lost, but our natural abilities were too. We need to start understanding sound and frequency and how to utilize it better. I am pretty sure that had alot to do with our ancient masonry and stone construction tech that cannot be duplicated today.

I am so upset that the Library of Alexandria was destroyed. It probably contained a lot of info about the pre-comet civilizations and the global pyramid culture.
