Did the pyramids inspire early human architecture?
Now that I've been inside the pyramid on Savathun's throne world, I've noticed that it seems very similar to Mayan or Egyptian architecture. I know the out of game reason for this, but it raises the question in-universe of whether or not the black fleet visited earth in the distant past. If not, I wonder if perhaps certain members of early human society received visions of the Darkness and/or the Black Fleet, thus influencing this aesthetic.
Keep in mind the insides of each pyramid seem to adapt to their owner or surroundings in some way that hasn't yet been explained. Why else would there be incomplete statues of horses around in one of them?
