If this is logic, it's purely inductive. We have no evidence for how likely it is that life form under water-like conditions.
- Teapot 12y agoWe have proof. So far we already have detected a planet with Earth-like conditions (called Earth). Life formed on it. Possibly several times independantly. The statistics for life on very earth-like planets are staggering.

- vbcr 12y agoBut this line of thinking eventually leads to Fermi Paradox. The apparent size and age of the universe suggest that many technologically advanced extraterrestrial civilizations ought to exist. However, this hypothesis seems inconsistent with the lack of observational evidence to support it. http://en.wikipedia.org/wiki/Fermi_paradox http://en.wikipedia.org/wiki/Fermi_paradox
