I think most people, with any amount of intelligence, probably realize that the chance that we are the only living organisms in the vast cosmos of this Universe as pretty low........but if there is life on other planets, and we were someday to actually 'meet' them/it, how likely is it that we will both be the same (or similar) size? In other words, what guarantees are there that they won't be giants to us, or vice-versa ?? SAVE FERRIS

In other words, what guarantees are there that they won't be giants to us, or vice-versa ?? SAVE FERRISI would imagine that life on other worlds is actually quit common, but not necessarily the sort of life we see in an average episode of DOCTOR WHO or STAR TREK. After all, what category will it fall into? Simple, complex or intelligent?
Simple life could be something like bacteria, fungi or a virus. Complex life could be something like an insect, a fish or a tree. Intelligent life could be something like an octopus, a chimpanzee or us. Of course, if it is intelligent, it might take on a form completely unlike us. It might look like a gaseous cloud, a viscous liquid or a machine - or it might be a completely disembodied intelligence.
If we ever do get to encounter alien "life", it probably won't be what we've been expecting or hoping for.

Water at liquid temperature is necessary to sustain life as we know it. How many planets have that? Liquid water on other planets could exist only under very, very specific circumstances. And then again, how are we defining life?

I do believe that "Simple" life is probably pretty common through out our vast universe... But, with anything other than "Simple" life, it is hard to say... Keep in mind... The "Classic" Dinosaurs that we usually think of, lived on Earth for several million years. The Dinosaurs may have been the most (or one of the most) dominant life form this planet has ever be host to... Modern Humans haven't even made it to ONE Million years yet... Perhaps, life on other planets might be more Dinosaur like, instead of Human like... And to be honest, if you really look at the history of our planet, Mankind is actually quite and oddity compared to most other life forms on our own planet that we know about... I think the odds would suggest, that we should expect to find, that Alien life is NOT like us... I think finding a "Planet Of The 'LIZARDS'" might be the best we can hope for, in finding any species even remotely like us...

So.…..this thread is an attempt to belittle anyone who doesn't believe in life on other planets?

I'd not be surprised if there is. If not, well, more room for mankind!

And then again, how are we defining life? It appears that water might be far more plentiful than previously thought.
It's scattered liberally throughout the solar system, on planets, moons, asteroids and, of course, comets.
So if water is a necessary element for life to exist, we might have more company then we'd previously realized. Of course, it might be nothing more than a few microbes.

My point was that most of the water in the known universe is in the form of ice which can not sustain life as we know it.

Yes, tardigrades are amazing but they are not very lively without moisture. Even in an environment that mainly consists of frozen ice, microscopic amounts of moisture can exist, even if only for a brief periods of time. Sometimes, that's all that's required. However, there's no way to know for sure what state the majority of water exists in across the galaxy, or indeed the universe. It could be a solid, a liquid or a gas.
In any case, Tardigrades can exist in such an environment, even if they are in a dormant state. And that's just the various types that have evolved on this planet. An equivalent alien species, if they were to exist, may possess a different set of strengths and weaknesses. And if they exist, there's no reason to believe there would be just one variety with one set of strengths and weaknesses.

I think there is life on other planets. I mean there are billions of planets in the universe to me it makes no sense that earth is the only one with life.

The chance there is other intelligent life, or has been, in our universe is high. The chance it is exactly like us is almost zero.
