The basic requirements for life are something to use as a 'building block' and something for reactions to occur in. These things happen to be carbon and water on Earth, and there are few other realistic options. Silicon and ammonia are one set, possibly the most likely alternative. Life also requires an energy input, so it would need a planet not so close to its star that it gets fried, but not so far that reactions take forever and a day. So while life does not require conditions exactly like earth, they must be similar, or at least equivalent. Much of near space is in fact filled with very low pressure gas (helium and hydrogen), so there is in fact a minute amount of friction. Incidentally, if you don't believe this, just consider how it is they can tell you the temperature of space - a complete vacuum doesn't have a temperature. As for speeds faster than light, I'll believe that when I see it. There are plenty of people who believe they have found loopholes in the laws of thermodynamics, and of relativity, but turned out to be mistaken. The theories may not work on a subatomic scale, or on a universal scale, but on a human scale they have never come under threat. 
The universe is infinite is it not? That means that there are infinite chances of there been life like on Earth in the universe.

Most humans haven't, although I am certain some have.
