I believe alien life is quite common in the universe, although intelligent life is less so. Some say it has yet to appear on planet Earth.

…only in the few universes that are like ours would intelligent beings develop and ask the question: “Why is the universe the way we see it?” The answer is then simple: If it had been any different, we would not be here!

Our population and our use of the finite resources of planet Earth are growing exponentially, along with our technical ability to change the environment for good or ill.

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

I think that it would be unwise of us not to believe that there is life outside of us, intelligent life. And so I do believe in aliens.

Earth might one day soon resemble the planet Venus.
