Why did life only generate once?[ What evidence do you have for this assertion? Life as we know it probably evolved on Mars, the conditions elsewhere in the solar system seem favourable, and there are at least 40 000 000 000 000 000 000 000 potentially observable solar systems that we haven't begun to explore. Beware of the Kruger-Dunning syndrome.
We don't see new life crawling around the tidal pools.Possibly the best place for it to evolve, but (a) there's lots of competition in a tide pool and (b) there's something like 8 000 miles of coastline to explore in the UK alone. The chances of anyone finding a new bug and proving that it had no organic ancestors are pretty small - we haven't catalogued all the "known" species yet.
Why does life have only one manner of replication? Is DNA the only answer?I think the answer lies in the question. If you define life as being the effect of replicating DNA, there cannot be another.
