I don't see how we could be alone. The universe is so large that there has to be planets very similar to ours. Not only that, but with it's extremely large size, who's to say that our environment is the only one capable of sustaining life? Just because it works for us, doesn't mean it's the only way.

Thinking about the size of the universe and what else is out there is something that I think about very often. I'm excited to experience the rest of my life just to see what else will happen on earth and what we will discover about the universe. I'm sure there will be a lot of things we could never have imagined were possible.
