Skyscrapers in particular will be interesting, given that to date no building over 200m tall has been voluntarily demolished[0], and there are currently 1340 buildings in the world over 200m tall[1].

(To wit, some of these theories may be correct, but it’s easy for one’s sense of skepticism to be blindsided by apparently compelling cases that arise by sheer chance.)

Anyway, future archeologists will find a lot of things about us, that'd surprise us.
We have a continuity with paleolithic religions' "fertility cults." From Venus of Duseldorf figurines in the upper paleolithic to Madonna statuettes in half of European homes today, Europe has continued a long tradition of Mother Goddess worship as the primary religious object. Clearly, we are a matriarchal culture.
The ancient Egyptian, Summerian & Hittite sphinx continues to guard most temples (especially gothic and neogothic churches) in the form of the gargoyle. Clearly gargoyles-sphinxes are very important to our culture....
It's interesting, playing this game. One thing that it highlights is how low key and nearly invisible "memes" can become. Gargoyles aren't really a part of our myths and religions (never heard a priest mention one), but they are all over European Christian churches and other buildings. Is this sphynx related? Seems possible. They look similar and are used in the same way architecturally as Hittite sphinxes. If they are related, it isn't in a way that's commonly known. What is the christian-gargoyle connection anyway? Is there a mythology that goes with these symbols? Do they symbolise anything to us or are they just a thing we're putting on houses of worship out of habit?
The Madonna is an important religious symbol, but not the main character or god of the religion. Still, you'll find more Madonna in household or public religious art than you will find Jesus art. Then, most Jesus art is symbolic (a cross) and we don't do YHVH (jesus' dad) art because depicting god was a Taboo. It isn't taboo in this milenia, so god is *occasionally" depicted in Christian art (eg the sistine chapel) but the ancient customer was different. The result is that churches don't seem to be temples to god, to archeologists.
Looking at a pile of art and symbols and stuff... I think we assume it had a symbolic or mythological sense to it. A reason that ancient priests could have articulated. In truth we are probably overphasizing some things that they though of as unimportant and completely missing other things that were vital to understanding the culture.
