How did they do it?

The Pyramid is estimated to have around 2,300,000 stone blocks that weigh from 2 to 30 tons each and there are even some blocks that weigh over 50 tons.

The common archeological belief is that the men that built the pyramids were not slaves but rather well paid and taken care of but did they actually have the technology isn't impercious to speculation.

Another group of new radicals believe that aliens built everything in Egypt during that time period and this is being corroborated by locational pyramid location markers on other parts of the world on the same plane and with the same type of identificational clues.

I do think it's interesting and I believe in the next decade we will be discovering a lot more truth about the Past the Present and the Future.
