Show me were a white boy built one during the same time. I will be waiting.
I wasn't around back them but I built a pyramid when I was 4. Does that count?
No. Your lego set doesn't count.
Tell me something, what was the hardest part about building the pyramids?
No, it wasn't cutting and moving the rocks, that was easy. The hardest part of building the pyramids was feeding the workers. The only reason nothing had ever been done on that scale before that time is that we were hunter gatherers, and it was impossible to gather a workforce large enough to build something on that scale.
For some reason, probably your abysmal ignorance, you think that the fact that the pyramids were built proves that there was a technologically superior civilization, despite the fact that no reputable historian believes that.
Real historians celebrate the underlying discovery of agriculture that enabled every subsequent civilization to fourish. If you really want to attribute the pyramids to your race you should focus on the real achievement, feeding everyone.
As a side note, it took roughly 100,000 people to build the pyramids. That is the same number of people it took to build the Panama Canal, and to send a man to the moon. Up until the invention of the internet it was impossible to get more people than that involved in a project. If farming got us to the moon, imagine what we can accomplish getting millions of people to work on the same project.
