Why are people downvoting you? There was a time scientists thought going 35mph in a car would make your brain explode. The point is, science can say anything, and until its proven wrong, it could be right. 100 years ago scientists told everyone that an atom was the smallest thing possible, and then they split that open and were like “HOLY SHIT, WHAT ARE ALL THESE THINGS???”
The point is, believe what you want with science. Until you’re proven wrong, you might be right.
Maybe there WERE two shooters in the JFK shooting. But BOTH shooters were Lee Harvey Oswald!!! Whoa!!! You didn’t consider time travel, did you???
