Question: Do aliens exist?

There’s a quote from one of my favourite books, the Hitchhiker’s Guide to the Galaxy:

“Space is big. You just won’t believe how vastly, hugely, mind- bogglingly big it is. I mean, you may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space.”

Space is so big, and so full of crazy things like neutron stars and supernovas, I find it hard to believe that somewhere out there among all the planets haven’t spotted yet there isn’t life somewhere.

The problem is that’s it’s all so far away that I don’t think they’ve ever been here though
