the builders did,artists maybe not?

But the artist's design the buildings, the artist's along with the
preisthood create the culture without which there would be no great
buildings. The art is therefore a very good indication of whether or not
they could have done it. Since it is clear they had no concept of
perspective, it is clear they had no concept of trigonometry no concept of
defining space in terms of X,Y,Z. That is so fundamental to undertaking
something of the magnitude of a pyramid, it is as amazing as a stone age
culture which had not invented the wheel making a racing car it's an
impossibility.
