Darnit..
Somehow my long post didnt make it.. figures..
Retyping and condensing:

I guess this comes down to 'because something can happen, will it happen in an infinite universe' or is it possible for something to happen once and only once if it has a high enough probability.

Probability is such a odd thing for us to deal with since we are wired for certainty.. and maybe I am having a hard time getting past my programming.. But I also feel like this question is one that is mathematically created and not one that needs to link to reality.

Consider: If I flip a coin an infinite number of times, there is a probability that it will come up 20000 times in a row. It is HIGHLY improbable but none the less not impossible. If we conducted this experiment would it eventually happen? Or another example of someone passing through a wall because of the perfect alignment of their quantum state. Possible? Yes.. Likely? no.

Systems like Human evolution (i'm not being human centric here, I'll even say a planet with my pet turtle has the same likely hood as me) are highly complex and the exact result does not have bias to the form. Given the exact same environmental conditions, its highly unlikely that humans would form even on this planet.. its random natural selection..

The fact that there is a non-zero probability of an event occurring does not seem to imply to me that there is a probability of 1 that it occurs somewhere.

I'm either too Dense, too Sane, or too much of a skeptic.. and when dealing with the concept of Cosmology, maybe Sanity is a drawback (need just a little insanity to get you to think further out of the box)
