Amazing, the theories that some human minds churn out.
They clearly have a strongly developped imagination to imagine such scenarios,
but their intelligence/analytic abilities are poorly developped and thus can not keep up
with their wild, irrational imagination.
It takes a well developped imagination to imagine such scenarios, but it takes a well developped rational intelligence to be able to tell that these theories are too far fetched, unconfirmed & unfounded to be taken seriously as a plausible theory yet and this latter is what these people(who post such youtube videos) are severely lacking.
You know I have such wild trains of thought too from time to time(like; The moon is a spaceship, Earth is hollow..etc), but I write them down as thrilling Science Fiction scenarios for a book or comic I might want to write later and
I don't go around presenting them as plausable theories about the true nature of our physical world.
Oh well. At least they gave us all a good laugh and that's never a bad thing.
