I've always thought that we, as human beings, would be naive and arrogant to pretend that we're the only life form in the galaxy.

I do believe there is life in outer space. Mathematically, there has to be, and if you believe as I do that there is a creator of the universe, then how can we be so arrogant to believe he created life here and nowhere else?

It's just too egotistical to think that we are the only lifeform in the universe.

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

I think it'd be pretty unrealistic to think we're the only planet in the world with thinking beings. It's kind of a strange conceit. Especially given how many universes there must be.

What we expect to find, certainly in our own solar system, are probably simple single or multiple-cell forms of life. To get to intelligent life takes stability of conditions over huge, long periods of time.

We agree that man was not created to survive in space.

We don't know why we are here and the context of our role in the universe, and the thought of an infinite universe. It's something the human mind can't really grasp. It's statistically impossible that there's not life on other planets.

People quite often think of the question 'Are we alone in the universe?' in terms of other civilizations out there: life forms that have reached at least our level of technological development.
