They remind me so much of thr engineers from prometheus too, like the way they acted and looked at the humans is almost identical to how they act at times, it's super fucking weird.

I know Germany had a giant head statue of what looked like an engineer like right before ww2 but the pictures of it have like been scrubbed from the Internet I guess.
