I'll give you a little background as to why I'm curious about this. I'm more or less a UFO fanatic, always reading and researching things related to alien technology and life. I came across this video that was taken aboard one of the shuttles that was orbiting our planet and they had recorded hundreds of unknowns zooming and moving around outside the ship. The objects obviously aren't satellites or anything of that nature, there are far too many, moving in whatever direction they please. Now, most people's first thought would be (other than skepticism) alien spacecraft!
Then I started thinking, what if these particular objects aren't spacecraft at all, not any kind of technology whatsoever, but actually some type of life form that had either evolved while in outer space or had evolved in one of our outer layers of atmosphere.
Now I know what most people would think, "There's no gravity, there's no oxygen, there's too much radiation," but we have found life evolving in the deepest reaches of the ocean where there is no light, no oxygen, and incredible temperatures and pressures and when I think about that it also makes me wonder, is there no limit to evolution?
Okay, so the question is: Assuming evolution is real, that things adapt to their situation, and assuming the universe is an unimaginable age, could life evolve in the vacuum of space, created from and surviving on space radiation and what little matter is out there? Could they be some type of being made of energy?
Here is the video (which, with or without seeing this video, it's still a compelling question):

I just wanted to put this question out there and see what kind of ideas and thoughts I would receive, thanks to anyone who replies!
