Hey Fearless, if I plucked you out of your mother's womb right before the first cellular division, and whispered into your nonexistent left ear, "eventually you will be able to ride a bicycle", I doubt you would have believed me at the time.
Only a fool puts limits on "possibility". Mathematically speaking, think about the chain of events that had to occur to put you in front of your keyboard here and now. And I'm not just talking about the semen marathon we all placed first out of millions in, I'm talking about from the formation of the universe forward. Considering that, are you actually going to tell me what's probable, and what isn't?
