They tell us all the time no one pays attention to what they are being told. The minute they say life and water in space people are waiting for the dis-info agent to tell us it hasn't been proven and all the nonsense that does NOT fit in with the rest of the show.
Comets are ancient bodies with an abundance of ice, some of which formed a few tens of degrees above absolute zero at the edge of the solar system, we now know that comets are really a mix of materials made

Stardust also had variety of other surprises. One of the most unexpected was the 2009 discovery of the amino acid glycine by a team of scientists from the Goddard Space Flight center. While perhaps not totally unexpected that a comet would contain amino acids it was unexpected that this molecule could be detected in the tiny particles that were collected at such high speed (six times the speed of a rifle bullet!). It was quite a technical triumph to develop the methods that made the detection possible and incorporated the use of isotopic composition to prove the glycine was not a contaminant from our own planet. The significance of this discovery is that comets must have delivered at least one amino acid to our planet before it had life. Because most stars have comets it suggests that all Earth-like planets obtain important pre-biotic molecules from space.

Exactly.
I get so sick when I read that NASA or/and any other so called Research Agency, tell us that life is impossible without oxygen and carbonate etc. Who says life must contain this elements in order to survive? Why can't life be based on any other element? I mean, we find all kinds of living microorganisms in a places where we never thought life is possible...

I have no idea what you are talking about because science already tells us that comets carry organic materials and water. That's not a secret.

It's also no secret that comets hold organic materials that are the building blocks of life, such as amino acids:

So the idea that science is hiding the fact that comets contain water ice and the building blocks of life is far from the truth. It is quite common knowledge that comets have water and organics. Many scientists think most of the water on earth came from comets impacts long ago -- and other scientists feel that those building blocks of life (although not necessarily "life itself") also came from comets.
...so, again, I'm not sure where you are getting the idea that this is some sort of secret knowledge that "TPTB" are trying to deny.

The process by which comets form is called accretion.
Individual atoms and molecules are swept up from space and slowly they build up the bulk of the comet.
This explains their low density.
Comets aren't cleaved whole off some smashed snow-planet.

It doesn't matter if the whole universe is absolutely swimming with life if we can't observe, detect it, communicate with it or anything else.
Invisible aliens are worthless and may as well not exist.
Water is not a rare thing in the universe.
Water is all over the place.
Largest known water reserve in Universe
Thus, life elsewhere is entirely possible, but, irrelevant so long as it's impossible to detect even the faitest hint of a sign of them.
