As fubar pointed out, only 1 Big-bang could've occurred according to the theory. But, even without taking it, the universe is nearly infinite( it keeps expanding at a ridiculous rate as we speak).
It's highly likely that there are other intelligent life forms out there. But then, evolution is a matter of millions of years. The human species is still very much at the infant stages. Maybe in a further million years or two, we could find proof of intelligent alien life !
It's a whole different matter that its not going to be in our lifetime.
