| DonFerrari said: About water being important to life in earth, that is because it's available here. The same for Carbon being the base for organic matter. There are experiments using Nitrogen or Silica as base (don't remember it fully). Its more like beings in earth evolved using water as important part because there is water here than we just have life here because of water... But that is all pretty in development. |
Some life (Bacterial) on Earth don't need Oxygen or water to survive, but instead thrive on Sulfur.
One form of lifes worse nightmare is another form of lifes perfect environment, you won't be seeing a polar bear surviving in the middle of the Australian desert for instance or a Kangaroo in the Arctic circle.
Arsenic, Chlorine, Sulfur, Nitrogen and Phosphorus are all possible elemental candidates that can replace carbon based life.
Most of the life we find will most likely be single celled, complex intellegent life will be a rarity, it's a rarity on earth even with only one species out of millions/billions capable of complex scientific thought. (Well, most of us anyway, we can exclude some of the more hardcore religious folk!)
There is proof that evolution exists from the observed changes in many virii and bacteria when an environment changes, there are also Macro and Micro evolutionary changes too.
Whether that conflicts with a religion is another matter entirely and personally, I couldn't care as I don't beleive in Religion and the hate and discrimination it brings upon the world.
