I don’t know why people think aliens built the Pyramids, but only ever the Pyramids at Giza. No mention of the others like at Saqqara or Meidum. No mention that we have a clear timeline of how they worked out how to build one properly because we have their trial and error attempts.
You think aliens came to Earth to build specifically just Pyramids, built this monstrosity, clearly fucked it up, and then went:
Aye lads, that’ll fucking do it
Ah shit we fucked this one up, eh guess we’ll take our super-precision laser tech that makes stones fit together like a glove and builds pyramids in the space of 40 seconds to Giza instead of fixing this one first
