You mean inside of a sun or so?

Current life depends heavily not only on RNA/DNA, but also water. I can not see how it is possible to have an information system (such as RNA/DNA) without water possible. Enzymes, even of extremophilic organisms, have a fairly small range where they can work. I think the temperature record is at about 122°C or so as highest temperature. At 150°C, if I recall correctly, ATP has a life cycle of 0.1 seconds or even less than that. Life is very fragile on every level.

In principle one could think of synthetic biology maximizing on all aspects including scenarios not constrained by "classical" life, but even then I can not really imagine how it were based on RNA/DNA without water. One could dispute whether metabolism belongs to life, but even if we were to state that metabolism need not be a defining feature (viruses may not need metabolism on their own, but they are cellular parasites, and in turn energy is required to maintain life, even if it is a dormant life stage such as seeds or what not), I can not imagine a system that could function differently here without a need for water.

If you mean any other solar system in general then it is pretty likely that life is possible on many of them, but logically there would have to be conditions that could yield life, and I think this is quite difficult. For instance, there is no life on Mars and never was, despite NASA trying to milk more money for a "quest" (besides, any such quest is pointless as there is already life on Earth, I fail to see the logic addiction here that more life has to be found "outside"; if the evolution of life is logical, and I believe it is, then it really is irrelevant how often this exists outside of this planet).

If you refer just to stars alone then I do not see how the conditions can yield life. The heat is extreme, it destabilizes almost everything. Even the radiation is deadly. Earth is rather rare here in conditions, see the term Goldilock planets.

Obviously not based on DNA/RNA. I think it is pretty lacking in imagination to believe that DNA/RNA in liquid water is the only possible configuration of atoms that could make a self-replicating and evolving organism.

  • Imagination is great for writing science fiction but it doesn't change the laws of physics that make the sort of organization needed for life impossible. You write "configuration of atoms" but there's no such thing within stars.

    • There is a sort of island of complexity in the parameter space of physics where we exist in a thin film on the surface of a rock orbiting at such a distance of a star of a particular strength.

      It is a bit presumptuous to dismiss out of hand that this is the only possible island of complexity in the universe and there are not other sets of parameters with similar entropy-fighting characteristics.

In Islamic teaching it is said that there are 2 other life forms. The first one is Angels, they are created from light. The second one is Jinn, they are created from smokeless fire. Jinn is like human being, they need to drink, eat, have sex, have family,etc.

I don't know how to prove that.
