For all our conceits about being the center of the universe, we live in a routine planet of a humdrum star stuck away in an obscure corner ... on an unexceptional galaxy which is one of about 100 billion galaxies. ... That is the fundamental fact of the universe we inhabit, and it is very good for us to understand that. -Carl Sagan, astronomer and writer (1934-1996)
Another way of looking at this fundamental fact: Our planet orbits around an ordinary star, on the fringe of an ordinary galaxy which is one of about a hundred billion galaxies, but in all our searching it is the only planet we have found in all this vastness that can sustain life as we know it. This is quite a distinction!
