Do you believe that alien life exists?

Question

Extraterrestrials have been imagined for at least 2300 years, if not longer. Epicurus wrote to Herodotus in 300 BCE proposing there could be "infinite worlds both like and unlike this world of ours", even ones inhabited by "living creatures and plants and other things we see in this world"

What say you?

It has been estimated that there are between 1 billion and 30 billion planets in our galaxy, and about 100 billion galaxies in the universe. Knocking a few noughts off for reasons of ordinary prudence, a billion billion is a conservative estimate of the number of available planets in the universe. Now, suppose the origin of life, the spontaneous arising of something equivalent to DNA, really was a staggeringly improbable event. Suppose it was so improbable as to occur on only one in a billion planets. Even with such absurdly looking odds, life will still have arisen on a billion planets - of which Earth, of course, is one.

Answer 1

Even though we may never contact them, I can't believe it *doesn't* exist. There are just too many other planets and yellow stars like our sun out there. Maybe there are other recipes for life, too, besides our own yellow star, oxygen, and water one. It seems too far a mental leap for me to say yes, definitely, we are the only ones in this whole entire universe.

Answer 2

I believe they are out there. A few years ago I saw a really bright speeding light moving through space one night that was going to fast to be man made or a comet or anything else. It was something alive and intelligent moving what looked like millions of miles per hour. I know there is life out there. Most of it might be in the spirit realm or some invisible form but I think the universe is full of life.

Answer 3

I think it's highly improbably that we're alone in the universe - the galaxy, for that matter.

However, I don't believe aliens have ever visited our planet. I think intelligent life such as our own is extremely rare and unlikely. But it's not impossible.

Answer 4

I am agnostic on this question.

I don't believe there is any current evidence for advanced life out there, but I believe that the mathematical probability is high that extra-terrestrial life exists. Although we don't know right now and it may be impossible to ever know, I would bet yes.

Answer 5

yes, i do...the proof? E! television, people magazine, entertainment tonite...clear and convincing proof that not only do aliens exist, but that they have turned a large segment of our population into brainless celebrity junkies, drooling and babbling over the latest antics of some vacuous untalented heiress with the morals of a crackw####, or which rich jerk is sleeping with which photogenic bimbo...as if what these people are doing is somehow newsworthy, relevant, or important outside of the cheap entertainment 'value'...

Answer 6

Yeah, it must exist elsewhere. It would be exciting to find life on other worlds. We would have something else to compare our life to. This would increase our understanding about the nature of life itself. It would be the greatest milestone in our species' existance.

Answer 7

Are not angels and demons ALIEN LIFE ?

YES

Not just universal but also inter dimensional.

( the stars like dust and the sands of the sea )

me

Answer 8

Parrotsh the thought. I think they're already here anyway.

Answer 9

it's not impossible but we have yet to see if there really are life out there.
