That was my thought. Why is it so damn complex? You’d think the solution would be simpler.

Sometimes complicated things are complicated.

the full equation for general relativity would take many pages to print, but Einstein notation makes it much shorter looking. This was not the case here.

Probably looks a lot simpler in A-normal form, with intermediates factored out.

Why would I think that?

It is. Some parts are repeated, the one which caught my eye was (zₐ’(rₐ)²+1)

I mean, if it was simpler it wouldn't have taken 2000 years.

I don't see the correlation here. Is every equation henceforth discovered guaranteed to be more complex than any before it? I hope not.
