Maybe silicon life forms consist of hydrocarbons like on earth but their DNA contains silicon instead of carbon. I'm not sure if this is possible though so correct me if I'm wrong.
@ConnorY71 if their dna contained silicon, that would mean the dna would be slightly heavier, so the dna would take a different shape and function, You gotta think more ahead. Also, silicon it way more conductive than normal carbon, so it'd be pretty cool to see how lifeforms are.
I think silicon based life is previous to carbon based life and is present in the lithosphere of the earth as unicellulars, we don´t detect it because it's small and surrounded by rocks also with a high % of silica. is that crazy?
@nicolasification1 IMHO not crazy but unlikely. Earth was formed 4,6 billions years ago, and first life arose 4,3 b.y.a. (i.e. in fact almost IMMEDIATELY in geological time scale). Silicon life (if it can exist at all) have a small chance to arose only if the normal carbon based life doesn't exist.
Sorry, my mistake: first life arose not 4,3 b.y.a., but a bit later. Age of oldest known microfossils from Australia (as far as i know) - 3,8-3,9 b.y.a
@AtollRu but how we can identify silicon based life in an silicon ambient f.i. in a rock. Carbon is easy because it's a gas and when it appears in a compost we may think of a certain action of life. and why it's not possible silicon based life joined our planet from the very beginning. Than silicon based life had almost a billion years to decide to continue as carbon based life. When silicon based life is possible it can stand high temperatures much better than carbon based life.
@nicolasification1 "but how we can identify...etc" - Well it's easy. We just need to find a some kind of complex molecules: something like amino acids, proteins or DNA, but with silicon instead of carbon. This is the main sign of silicon life. But it is obvious there is no such things on our Earth.
"silicon based life had almost a billion years to decide to continue as carbon based life" - hope you kidding )))
PS Frankly I hardly believe in silicon life (no matter on Earth or somewhere else)
@AtollRu Alexander, please don't think that what we know or hear at the present is all what exists. I have some strong evidences it's not. (I work with bacterias). To analise/ find certain things at least you have to know what you are looking for, and that is exactly the problem. Inexplicable rising ups of life occurs in silicon environs.
@nicolasification1 OK, I'm agree, but this is just an interesting example of adaptation. There is nothing "alien" here! These bacterias live in the arsenic-filled lake, so... And btw phosphorus isn't main element of life (unlike carbon)
@AtollRu C,H,O,N,S,P are considered main elements of life, NASA said that it in a special case can be C,H,O,N,S e As. I am not so browbeated by that also, but I work for 18 years with bacterias in agriculture in research and practice and their comes a moment that you get the feeling that there is an underlaying something that is involved, When you don't know where to look for it's difficult to find anything, apart from the fact I'm not NASA and I don't have by far the means to investigate this.

@ConnorY71 very possible, we simply dont know enough yet.

Wow, wow, wow. we have silicon based life here on earth..
I mean look at Pamela Anderson and Carmen Electra.

@nicolasification1 and suddenly there appears instead of phosphorus an arsenic needy bacteria.
