What is the probability of finding H2O on other planets? Zero?? life must exist if water is found, that's why NASA is spending billions of dollars just to find water on other planets.
I think the big bang "Theory" can proves it, however I still don't know what do we mean by "universe", is it the space that we know, or it also inclues beyond space "Vacume !". What do you call the "No Space/No Time" before the big bang?!
