Here goes another one.... (keep up at the back)....
We live in an infinitely large universe containing an infinite number of stars around which orbit an infinite number of planets.
Lets say 1% of these planets is capable of supporting life.
Any number smaller than infinity is by definition a finite number.
Any finite number divided by infinity is near as makes no odds, zero.
So this means that the population of any given planet is zero, so if you're talking to someone else, then you must be imagining them.
Or indeed, they must be imagining you.... discuss
