is there really such thing as aliens?

Answer 1

There must be some kind of life form on the billions of other planets that must be out there. As far as little humanoids abducting us and probing our bodies, it seems that it's mostly a cult belief with absolutely no physical proof.

Answer 2

Obviously so far we don't have any direct evidence that life exists anywhere but on Earth. However, it seems likely that wherever conditions are right, life will evolve. In the past decade we have discovered that planetary systems are common. Where stars form, planets also tend to form. The odds are that there are many planets out there where life could form, and if it does form wherever conditions are right, then it's highly likely that life is abundant in the cosmos.

But we don't know anything about what kind of life. Is our type of life (the kind that evolved on Earth) the only possibly type of life? Maybe, maybe not. If not, the likelihood of life elsewhere goes up dramatically. Does it always have to evolve into intelligent forms such as us? We don't know. (My personal guess is that so long as conditions remain good for life to exist, evolution will eventually produce intelligent species such as us, but that's just my personal guess.)

If intelligent species evolve and develop sufficiently advanced technology, can they travel to other solar systems? Again, we don't know. We actually could travel to other solar systems now, but it would take a really long time. We'd have to have spacecraft capable of supporting multi-generation crews to do it. If we could accelerate to a high enough percentage of the speed of light, we could get to anywhere in the universe in a single human lifetime, based on clocks on board thatr spacecraft, but to Earth-bound observers watching the journey it would still take a very long time. My guess is that interstellar travel is so difficult that it probably doesn't happen much, if at all. But again, that's just my guess.

So the short answer is, yes, there probably is life out there, and yes, there probably is intelligent life out there, but no, they probably aren't coming over here to mess up our crops and abduct our neighbors.

Answer 3

We are already here. Over the centuries, your planet was a curious place to visit once or twice and was not considered very interesting . Sure, your wars showed us how undeveloped you are as a species. Your infantile,(in cosmic terms) dependence on god concepts does not bode well for you and neither does your penchant to breed beyond your planet's ability to sustain you. We are now showing an interest in you because it is not often that we get to observe a species commit suicide. You are so close to maturing as a sentient species and it will be a shame to see you kill yourselves. There are just not enough of you becoming rational enough to force the issue. You let the least among you determine your fate, so be it.

Answer 4

I think Yes, there is really such thing as aliens.

Answer 5

Although we never see real-life aliens (a.k.a. extraterrestrial life), scientifically they might exist. Recently, NASA is trying to detect any life-form at Mars because of presence of water. Aliens don't have to be large as humans or even larger. They can be as small as bacteria or other uni-cellulars. SETI, another body conducts astronomical search for radio activity that would confirm the presence of intelligent life.

Answer 6

Sure! They watch us in their cloak ships and laugh at how primitive we are compared to them. I bet they record people doing stupid stuff and sell the video to the general alien public on thier home planet to make money. so they can buy their alien girl friends hot alien stuff and get lots of alien booty :P

Answer 7

Yeah, illegal mexicans are illegal aliens. If you are talking about space, then there maybe aliens but i doubt it. We need to find another "earth" first.

Answer 8

Yes we do exist.

Answer 9

Certainly. But if you mean from other planets, no.

Answer 10

99.9% yes.
