      We think that there are 1,000,000,000,000,000,000,000 stars in the observable universe, and that lots of these stars probably have planets. I think that there is a very good chance that there is some form of life out there someone on at least one of these planets, though it is probably very different to the life we see here on Earth!

      Yes, absolutely! There are a huge number of stars in our galaxy alone, and our best estimates say that the galaxy should be teeming with intelligent life. It’s actually quite puzzling that we’ve not made contact with any yet.

      Not only that, but Mars had the right conditions for life for much longer than it took life to develop on Earth. This life wouldn’t have had time to develop into anything more complicated that single celled organisms before the environment drastically changed, making it uninhabitable.

      I’ll be very surprised if we don’t find evidence within our lifetimes of there once being life on Mars.

      Yes! There are more stars in the sky than there are grains of sand on earth. If half of those stars has a solar system, then that is a lot of planets that could potentially have life. I would find it very strange if earth was the only planet in the whole universe with life.
