Was the polio virus that ravaged young people in particular, introduced by extraterrestrials to undermine humanity?

This is a perfect example of a virus that was repurposed and re-engineered by extraterrestrials to have devastating consequences, and this was true of smallpox as well. The problems posed by the microbial realm with the many deadly pathogens that can be quite devastating, particularly when highly contagious, are extraterrestrial in origin across the board, and this parallels quite closely the story with natural disasters. Many deadly adversaries are present in the environment and taken for granted as being natural when the plan of Creator for the world of divine human was to be a gentle and loving world in which there was no place for a deadly adversary of any kind. Earth was configured as a benevolent and loving nest to house human culture and to be an enjoyable, inspiring, and joyous environment. There is no place in this picture for deadly disease germs that can wipe out thousands to millions of humans who die with great suffering, or whose lives are taken through violent upheavals in the environment through severe weather or instability of the Earth’s crust, and so on. Such happenings are not part of the original configuration of Gaia and the biosphere it contains. They are artificially induced sources of destruction done by extraterrestrials and their higher technology, to drag down humanity and allow the extraterrestrials to feel victorious as conquerors.
