The universe is far beyond what we really know, and possibly far beyond what we want to know. My senior level astronomy class may have only lasted one semester, but think of this.
We could be remnants of other civilizations. A star supporting life on another planet similar to ours could have super-nova'd and as a result blew everything over there to bits and those carbon atoms and all of that other good stuff just so happened to land on Earth after who knows how long of a trip. There's a million possibilities but we'll probably never know.
Space is big, but humans will never know how big until we can travel faster than the speed of light. Possible? Maybe. We just have to find out how to do it. There's only 200 billion something planets in our galaxy alone, so at least another one of them has to be habitable, right? We cant be the only ones here. Maybe those aliens (If they exist) will figure it out one day.

Who else just loves the universe?

Oh, and here's a list of pictures off of the NASA website of random space stoofs.
