| Rath said: @Highwaystar. Out of genuine interest (and almost entirely off topic) what elements apart from silicon and carbon due you think life could form from? Or was that just based on the idea that the human species really doesn't have anywhere near enough knowledge to rule out other forms of life? |
Well I used Carbon and Silicon as an example. I guess that outside of these two we know of no other element that could act as a base for certain (and silicon requires us to make several assumptions at that). Other proposed bases for life are purely hypothetical with our current knowledge, such as nitrogen and phosphorus.
The point that I was trying to make is that some people assume life has to have the exact same of combination as Earth to form, which I see as just untrue. So yeah, based on the idea that we just don't have enough knowledge of the Universe to rule out other forms of life.
