So far we've seen no verifiable evidence of other sentient species. That said, I believe with some certainty that somewhere in our galaxy at some past, present, or future time, a sentient species did/does/will exist.

Why haven't we heard from them?

Perhaps they are not technologically advanced to be heard. They may be mastering stone knives right now, or experiencing their own Rennaisance.

Perhaps they are here right now. Any species sufficiently advanced to travel interstellar distances would be able to hide or masquerade with ease. That Boeing 737 that flew by may be a surveillance craft.

Perhaps they are so far away they will never notice us and vice versa.

Perhaps they existed a million years ago and died out.

Perhaps they will exist a million years from now.

It is really impossible to know for sure.

The Drake Equation suggests that there is sentient life out there. The Fermi Paradox casts doubt. Play around with the calculation form at the second link and see what you think.

A couple of the other answers pretty much have it right. To go into a little more detail, we know that life exists in the universe, because we are here. So that is proof life can exist. That sounds pretty obvious, but you have to mention it since is is the only concrete evidence we have of life in the universe. If we can exist, then presumably life in other parts of the universe can exist.

There is an equation called the Drake equation, which basically says if you have so many galaxies, and we estimate so many stars per galaxy, and we estimate some of these are the right size and age stars, and we estimate a certain number of these have planets, and we estimate so many of these have the right conditions for life, and we estimate so many of these developed intelligent life, ect. the actual equation is : N = N* fp ne fl fi fc fL

The biggest problem with the equation is except for the number of stars and galaxies, we don't know what numbers to put in! We are starting to know about how many planets we should expect, but this is a recent development. We don't know how intelligence develops, we don't know if an intelligent species will necessarily develop radio and space travel. There are too many "ifs".

The general consensus is that life does exist "out there". There is less agreement about intelligent life, and much less on the space traveling aliens of star trek and other sci fi. If you want to know why that is, look up "the fermi paradox".

I don't know, because for one, I don't know what you mean by "aliens."

If you mean people like us, that is one thing, and the answer has a smaller probability.

if you mean all life forms, which could take in a huge volume of things from the tinyest single cell organism to complex cold and warm blooded animals with varying levels of intelligence even equal to or exceeding that of mankind, then there is a larger probability that yes there is life out there somewhere.

If there are a billion stars (and the total number is not completely known yet) as the center of a billion universes, who knows how many planets there are in total? Now of all of those (number unknown) at least one of them must have conditions similar to those here on Earth which would be fertile ground for the development of life forms somewhat similar to our own, though not necessarily in the same shape or configuration. When that life form will develop the required intelligence to communicate with us is unknown. The time may have come and gone while we were in another stage of our own development (Ice Age maybe).

So, it is not a matter of having equivalents "Now." but the possibility that they would exist simultaneously at an equivalent intelligence level...and that makes matters somewhat dimmer in actual possiblity.

Why not say yes to the possibility of one in 200 billion? It is possible. Will we ever see them. I think not.

We are real. 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.

I can't say yes or no. But , you may be interested to know that advanced meditators ,, and astral travellers (out of body rituals) generally warn against them. And this is concensus throughout the cultures in the East ,, where the attitude is to regard , rightfully with fear.

We have Americans meditating in Thailand. If you know the returnees , ask them about this "power man".

Once they figured you are asking of a "power man" not of Earth , half of them will stop the conversation.

I cannot say if they are e.t. but such concensus behavior is wierd. And of course their tenets , warn of this beforehand.

With hundreds of billions of galaxies in the universe, each containing hundreds of billions of stars, each of which have potential to have hundreds of thousands of planets orbiting them, I'd say it's very likely.

Illegal aliens are definately real. There is no proof of any extraterrestrials...so, they're not real until we can prove it...

Statistically they'd have to exist in some form or another, even if they're just lichens.
