No. Wrong. Architects and Engineers design the building, artists paint
pretty pictures.

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 actually clear that they did. Of course if you only see a
selection of their art that has no perspective then it is easy for the
priests of your religion to misinform you.

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,

There is no need for trigonometry, geometry is what architects use
today. In any case there is no need for any sort of drawn plans as a
model can be used to create the design of such a structure.  It is also
obvious that the building is a progression working from the previous
successes and failures.

it is as amazing as a stone age
culture which had not invented the wheel making a racing car it's an
impossibility.

Strawman argument. Learn what else the egyptians did.

Actually you should also learn what 'stone age culture' did achieve.
