There's no such thing.
Have you ever seen a REAL alien, not in movies or on books but a REAL alien?
No. But would like to.
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.

doesnt common sense indicate that there are aliens out there?
a mexican physicist developed a theory called "Alcubierre warp drive" which creates an entirely plausible solution to FTL speeds [faster than light]
there are theories involving nuclear explosions as a means of propulsion through space [being no friction, there would be constant acceleration when given force.
there are also ideas of massive sails that would be the target of a giant laser [not the lasers in the movies, a focused single wave light source.] which would, if you dont know now you know, create a thrust, again accelerating the shuttle into deep space...
i wouldnt be so certain that the life that is most certainly out there does not have the technology. you do not know what type of conditions they are accostomed to. you dont know what type of materials they have available. do you suppose that ALL the universe is just like the earth? that is entirely unlikely...
