That’s basically the way a zoo works. It houses critters from far-flung places so you don’t have to travel to their habitats to study them.
Assuming we live in one, that is. I find it probable.
Imagine someday the monkees in zoos get smart enough to understand iron bars and snack stands aren’t “natural”. They’ll be looking at the various man-made items and asking each other how to explain it. When they get even smarter and are able to understand the concept of “zoos”, they’ll grasp that they are inside same.
We only have to consider the Moon. It shouldn’t be there, it should be much more massive than it is (it’s as if it has enormous voids inside), and it shouldn’t ring for hours when struck by a foreign object, as it does.
The Moon imparts a great deal of additional angular momentum to the Earth-Moon system, which results in greater stability of the rotational period. The tides generated by the Moon help create niches for thousands of forms of life. Yet if the Moon was as massive as its size calls for, our tides would be more extreme.
It’s as if the Earth-Moon system is designed to form a habitat for a staggering array of life forms.
