The problem is not the arise of life on other worlds but if that life develops sentience then technology then interstellar space travel.......many factors need to come into play for all that to happen. Ponder that for a while Cliff......
Cliff, The math has been done many times before and the original formula was called the Drake Equation. Depending on what variables one plugs into the original Drake Equation you can get as little as one sentient race or tens of thousands or more...in our Galaxy. Obviously the number would be far greater when one includes all the other galaxies. Life could be abundant out there......the odds that sentient species evolve is much less and the odds that they survive to reach tech levels to travel in space is even less.
Earth is on the edge of a very basic galaxy....even in our own galaxy would a sentient alien race find their way to earth out on the outer rim? It's possible but I think those who believe in all these aliens buzzing around in our skies are wishing on a star.
The difference is time. The Drake equation was calculated on the basis for life's existence during THIS time frame. This does not apply in these calculations.....HUGE difference.
Were talking rise and fall of many civilizations.....over billions of years.

I'll say this. If the universe grows to an infinite size then anything with any probability (no matter how minute) can also occur an infinite amount. Infinite planets, stars, aliens, etc. That's the beauty and problem with infinity.
Now, if the universe does not go on forever (infinity) you can forget what I said and carry on.
