Pyramids are trippy. I saw a documentary on it a few months back stating we didn't have technology until recently to construct the pyramids as precise as they had been and even with todays technology it would be nearly impossible to reconstruct it to be as precise as it is now. Given that people think they did it with a hammer and some string i find that theory nearly impossible. There is however evidence in the bible that could suggest that early civilizations were very much advanced in technology. A bible teacher who i highly respect: Chuck Smith stated this in regards to Genesis where it states that nothing that mankind cold imagine would be impossible: the Lord looked upon the scene of the building of the tower of Babel, He spoke of how that men gathering themselves together had advanced so far in their technology, that nothing that they determined to do could be withheld from them Now i can see how this statement is controversial and would be laughed but it would actually explain quite a bit regarding to what we have found throughout history.
