If you care to look at the history of extrasolar planet detection, a subsection of the extrasolar planets article. You'll see that as far back as 16th century the Italian philosopher Bruno thought that stars could be 'other suns;.
There is much more to the history - a nice read indeed. This indicated that the possibility of detecting other planets beyond our own solar system has been research research material for a long while. A few retracted claims- but science wouldn't be science without transformational practise in its processes.

As has already been stated, it's not that the skeptics doubt ET life, or even intelligent ET life...they doubt that we are being visited by them.
And, there is a solid reason for this doubt. Traveling at the speed of our fastest rockets, it would take us hundreds of years to reach even the next closest star! That's a long trip....(especially if we get there and it's one of the more common systems, and no life world is there...indeed, we've detected them elsewhere, but not in our closest neighbor).
The thing is, the sheer statistics suggest the our galaxy is teeming with life, but even still, it's only a small percentage of star systems in the galaxy that are likely to harbor it. If it takes us that long to reach just the nearest one, it could take us (or theoretically, any aliens) numerous lifetimes before stumbling upon another.
However, what the skeptics doubt, is that these aliens have developed some means of travel that defies physics as we understand it. So, if these beings have developed an interstellar drive that can somehow bridge these distances, THEN we have a much higher probability of visitation.
Sorry, I'm a skeptic and I doubt that there is any other life than us in creation. Now, since this is an Alien & UFOs forum, and we are dealing every day with the reality of UFOs it could be argued that said UFOs contain a life form that is not human and that they come from somewhere else in the universe. There is no evidence for that assumption and until a proven alien life form makes a major public appearance and somehow provides the kind of irrefutable evidence that proves he's/she's from somewhere else in the universe the only consideration we can give said UFO occupants is that they are from the future. Major leap in theorizing but it sounds better than a space traveler.

So I don't believe it, because the size of the universe is not good enough proof.

Sounds like an emotional choice if you ask me. The evidence is overwhelming for life by the fact you see one example of it thriving right before your eyes.

1) Liquid water has been detected and all but verified on other celestial bodies, even in our own solar system. From our own planet, we know that where liquid water can be found, the possibility of life isn't far out there.
2) We've detected other worlds around other stars, that are in the "life-zone" just as Earth is.
3) Sheer statistics put the probability of ET life as almost a certainty, whether you use the Drake equation or expansions of it.
4) Other evidence includes witness testimony of descriptions of creatures that do not fit any known creature on Earth. (and it's highly improbably an intelligent species would have escaped our attention, if Earthbound, therefore, the conclusion they are ET in origin is quite logical).
But neither you nor I have any idea how unique our life on Earth is, because we don't know how it came to be. You seem to be assuming that if we take some water and chemicals and lightning (or whatever) and shake it at the right temperature long enough life is somehow automatically, magically going to happen. Experiments so far have determined that if you do that, you get some amino acids, but amino acids are a long, long way from even the simplest form of life, with DNA that crawls around and eats and has a consciousness.
At this point in time, we have some possibilities, some debatable evidence, and some conjecture that life might exist elsewhere, but it's still not nearly good enough to say for sure that it does. I personally don't "believe" one way or another about it. But that's the way the facts as we know them stand right now.
Another reality, maybe?
From the beginning of time, human beings have been bugged by odd creatures -- ghosts, demons, leprechauns, dragons, hairy Bigfoots, sea monsters, mermaids, thunderbirds, and so on. Are all these things possible evidence of extraterrestrials, or are they maybe from a little closer to home?

....it would seem an awful waste of space if we were the only life out there....

You said there wasn't "evidence"...there is. I'm not saying there's "proof", but there is evidence, and it seems we can at least now agree on that...
But leave it to Nature to fill the gaps. I tend to think that both space and time are permeable, a bit like a sponge, and if you approach it the right way, you can zip right in and through it however you like. Maybe even without a lot of "power" as we understand it. I also tend to think that every once in a while Nature pops up with a random wormhole of its own, big enough to suck through a bacteria or a fish or even a whole planet, and send it sailing off randomly into space and time. I personally think that's what accounts for the ongoing expansion of the universe (both forward and backward in time). Stuff "falling out" of it.

Modern ideas in physics actually do more to support rather than refute these ideas....but, if so, this could also open the door to interstellar travel, if moving through vast distances in space are possible.

Well, you are one of a very small minority of people who believe this. Why do you doubt that we are the only life form in the universe? What do you base that assumption on? Also, i have to ask this, are you religous?
