We know so much, yet so little about space. When you think of how large it actually is, then look at what we have actually explored it's insane. There is the famous photograph of earth in our galaxy taken many years ago, and you can only just see the blue twinkle. Which makes you think, is there life up there?
I believe there is. Especially when NASA are finding planets in different galaxies that are extremely similar to Earth and have been said to be capable of holding life.
I wonder if we'll ever find out?
