Re: are we alone in the universe?

i believe ken posted earlier that if their were life it would have DNA but i thought allot about that. if DNA is formed by specific amino acids and these in turn are created by specific reactions with certain chemicals than the only way aliens would have a similar form of DNA would for their to be similar conditions present. given the extremely distant probability of earth having a twin i doubt life will have similar building blocks. however how would other chemicals or the same chemicals form with completely different environmental stimuli (like extreme gravity or radiation). if we meet life biologist will have a field day and much of the founding blocks (DNA or even amino acids) will be insanely different from what we know. this of course assumes that the life we meet even has a chemical biology.
