Ancient Egyptians were apparently more advanced the further back in time we go.

Here before some slack-jaw comes and rug-pulls the conversation by derailing it with a meme of how aliens did it and instead I bring it up myself.

Highly doubtful that aliens did it. And only the fringe minority actually believe and say that.
But they might as well have had fucking laser-cutters, considering how smooth and perfect some of the ancients’ work is. At least they were technologically way ahead of the curve, more than we tend to give them credit for. Whatever that technology was.

It’s insane.
