Look at it from the open universe aspect, where there is an infinite universe with infinite matter, which would therefore create infinite anti-matter, energy, and just about everything else. If, indeed, there is no limit, than anything is possible given ample time to develop. If the closed universe model is more your suit, then assume that outside of the universe, there is something else, or nothing at all, either way humans are incapable of understanding it (currently). This means that more than likely we are increasingly fallible, and things that we find to be impossible are truly not that at all.
