Why Haven’t We Seen Aliens?

If there really is alien life elsewhere in the Universe, then it’s reasonable to ask why we haven’t seen it.

This standalone book uses our knowledge of the universe, some simple maths and a little bit of intelligent speculation to take a sober look at the chances of our actually meeting alien life.

After all, we will only meet up if both of us are in the right place at the right time. The Universe is a big place – and it has been around for a long time. Perhaps we were “out” when they visited us?
