And what humans did with our limited, non-alien brains is pretty damn amazing.

The Ancient Egyptians, as far as we know, invented the pulley. But somehow they were too primitive to drag around blocks of stone if they just had a whole lot of people pulling on them- although they were non-primitive enough to put them on a sledge and wet the area in front of that sledge to make the ground smoother and slicker.

It sort of seems like they had the same brains as our brains that came up with all of this modern technology. And, considering these Ancient Aliens folks seem to think aliens created us, brains and all, you'd think they would see it that way.
