There are several good explainations, like the one that
sees the origins of life on earth in a primordial
environment that has been very different from the
world we know today. 3.5 billion years ago the earth
has been quite hot and hostile, and there has been no
blue skyes since the atmosphere had no oxygen ;-)
A good reading on this subject is: "The Fifth Miracle -
The Search for the Origin and Meaning of Life" by Paul
Davies (Simon & Schuster). Especially the chapter on
"super bugs" and their properties. Really spooky...
All the best,
