condtions are not like earth, no water, no oxygen to breathe etc., but isn't it possible tht life on some of these planets are so much more advanced than ours that they don't need these things and edifices like we do. They are so much more advanced than us thaat they can see us and we can't see them, for example?

the human mind is so very limited and finite, and the human creature is so very arrogant and full of itself, it is amazing there is anything surviving on this planet at all.
there is life so unimaginable to the human mind, there are no words for it. yes child there is life on other planets in the universe, the human race is too primitive and backward to understand it, let alone find it. and that is a good thing, as the human creature destroys all that it touches and sees.

Chemistry is a universal phenomenon. It is hard to think of another way a lifeform could store and use energy without using the most reactive gas in the universe - oxygen.
The galaxy is now known to have lots of organic molecules (carbon based) in dust and gas clouds. It is therefore fairly certain that if any other lifeforms exist out there, they would be based on carbon, oxygen and hydrogen.
The organic molecules are precursors of the most complex molecule that we know of in the universe - DNA. All life on Earth, however it derives is energy, is based on DNA. It is just a very complex carbon based molecule, and the universe seems loaded with carbon based moelcules.
Also, it is not warped thinking to suppose life is unique on Earth. There a brilliant scientists that have show that in spite of the quadrillions of stars in the universe, the chances of a freak coming together of organic molecules to create soemthing like DNA is many quadrillions to one.
So, mathematically, it is very reasonable to suggest that life on Earth is unique.

Well, no life like the one we know, which is the only one we know about.
That statement about other planets not having water and oxygen apply only to the other planets in our solar system. There may be planets that we have not discovered yet, around other stars, with all the right stuff AND perhaps with life already on it.

Its completely possible, but until and unless we have a way to detect this kind of life, we won't know for sure.
When they say "life" they are implying "life as we could recognize it", meaning bacteria, microbes, plants or higher forms. For any of those, the requirement (at least as far as we know) is liquid water. Oxygen is not a requirement of life - on earth there are anaerobic bacteria that cannot survive in an oxygen atmosphere.
But we could assume anything about "more advanced life", and we would have no way to prove it one way or the other.

That's very unlikely. If anything, life on other planets would need other things, like CO2 instead of oxygen. But think about this: If the universe goes on forever, in all of those trillions of planets, you'd think at least one has conditions suitable for life, right?

I'm not sure that it matters if there is life on other planets. The chance that we could interact with them is close to impossible. Take our own planet. We can't communicate with any other creature on it except other humans... and honestly, we don't do a very good job of that. And the creatures on this planet have a good deal in common. From being carbon-based to eating the same food. I agree that another "intelligent" species would have so little in common with us that they would have about as much to offer our species that we could comprehend as we could offer chimpanzees. Nothing really, except to not destroy them and let them live their lives.

I firmly believe that every sun ( star ) has at least one class m ( life sustainable ) planet with intelligent life be they advanced or lesser advanced and their isn't anyone on this planet that will ever convince me otherwise. I may not have the facts but I still stand by my belief.

Life like we know it isn't the only life possible, scientist have found life in magma, in the deepest parts of the ocean where no light and for the most part no warmth. Life has likely evolved along other lines in other places, the universe is a huge place.

Certainly the earth can't be so warped in their thinking that in this vast endless universe that this tiny planet is the only one inhabited.

But it would have had to have the things that sustian life before it got so advanced it didn't need it.
