The trouble is that when archeologists rummage in the ground, dig out temples and sites of ancient settlement, then they pull up on the surface of the Earth what the Moon had been closing layer by layer and what was being rested under the ground during millenniums. As a result, what was wandering in the darkness during millenniums is pulled out and merged into Space. And the first blow from this part of Space infected with vices is given to people who are part of Space as well.
