Well, YOU'VE just spewed the current archaeological line of BS!!! I'm not saying anything about aliens. I'm saying that based on what we KNOW of these peoples, most of these megaliths SHOULD not have been possible.
Talk to men who move heavy things. Ask them how to move a block of stone weighing from 50-400 TONS! And some weigh even more.
Getting the picture?
I know these stones were quarried, transported, and carved. But using what tools, what math, what language, what math, what technology? In other words, HOW DID THEY DO IT?
There are a lot of missing pages to these stories, because based on current archaeological dogma, again, these megaliths SHOULD not have been possible.
Regarding the Great Pyramid. There are 2.3 million stones. If built in 22 years as was written, that means that a stone must be cut, transported, and fitted every 5 minutes, 24 hours a day! Every 5 minutes of every day for 22 years. Oh really? Since they likely did not work at night for various reasons, the numbers become even more insane. No way.
