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.
And as I have always said, the only thing more scary than knowing we are not alone in the universe is knowing we are alone in the universe.
I believe in aliens. I think it would be way too selfish of us as mankind to believe we are the only lifeforms in the universe.
I think anybody would have to be with out common sense to think there weren't aliens. There are billions of planets, and I am convinced Earth is not the only one that's inhabited. It would be quite an ego trip to think that. I think about it all the time.
I don't see why there is no intelligent alien life in the universe.
It's naive to think we're the only living beings in this universe.
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.
Give consideration to the fact that alien astronomers could have scrutinized Earth for more than 4 billion years without detecting any radio signals, despite the fact that our world is the poster child for habitability.
The statistics of life out there and the statistics of intelligent beings and advanced civilization is a certainty, the way I look at it. that It has not been accepted, because we've been in an anthropocentric era.
I think it quite likely that we are the only civilization within several hundred light years; otherwise we would have heard radio waves.
