The maths are so incomprehensible that, apparently, it makes it not just likely that there are aliens, but in fact likely that there are aliens who are human-like. If the theory (which is in fact likely) that the universe is just the limits of our observations and there are in fact probably hundreds of billions of universes ... it then makes it likely that by sheer coincidence there will be other entities living our exact lives.

Tis indeed mind blowing stuff.
