We will create life from inanimate compounds, and we will find life in space. But the life that should more immediately interest us lies between these extremes, in the middle range we all inhabit between our genes and our stars.

We're going to understand that there is life on other bodies in the solar system.

There may be aliens in our Milky Way galaxy, and there are billions of other galaxies. The probability is almost certain that there is life somewhere in space.

Life exists throughout the cosmos and is a consequence of matter in the universe.

We're constantly re-evaluating the potential for life. We're finding it where we didn't think it could exist, such as volcanic vents and other extreme conditions like under arctic ice. We're finding life in these incredibly harsh and dynamic conditions, so we're having to re-evaluate our own ideas of what's possible on this planet alone.

Should we find a second form of life right here on our doorstep, we could be confident that life is a truly cosmic phenomenon. If so, there may well be sentient beings somewhere in the galaxy wondering, as do we, if they are not alone in the universe.

I am confident that life once thrived on Mars and may well still exist there today.

I believe that there may be intelligent life on other planets.

If this is the only planet on which not only life, but intelligent life, has arisen, that would be very unusual.

Perhaps, as some wit remarked, the best proof that there is Intelligent Life in Outer Space is the fact it hasn't come here. Well, it can't hide forever - one day we will overhear it.
