Forget the Pentagon Report, math can tell us if aliens exist
People areconstantly seeingthings in the sky they dont understand. But for some sightings, theres no known explanation. The problem is that people jump to the conclusion unknown = aliens. And when you think about it, this is fairly odd. Anyway, I like to do maths instead. It tells us how we should update our beliefs based on new evidence. There are two factors in the equation. One (second bracket) is how likely we think aliens are....
