Pi is an infinite series of non-repeating digits, and yet you will never find the letter A in pi because there is a 0% chance of the letter A being a digit in a decimal system. By the same logic, infinite possibilities do not guarantee that every conceivable state occurs, if that conceivable state has a 0% probability. As finite beings, it is very difficult for us to accurately distinguish between a 0% probability and a infinitesimal probability, so we end up circling back to "we don't know"

That theory suggest that everything that can happen, will — but even then, things that can't happen, won't.
