food for thought
why would they be any different than us?
when scientists research different species and “no contact” tribes, they try to remain hidden so they can observe without disturbing
makes sense that IF we are being visited, they would do the same: take samples, take some back for their “zoos”, observe, etc
just an explanation that makes some sense............
If they can manage interstallar/galactic travel they are definitely either scientific or magical. So your hypothesis is a valid one.
Some abductees have reported seeing sizeable intergalactic zoos on some of the super huge mother ships far out in space.
