life actually probably formed on earth several times, just to be wiped out by impacts powerful enough to sterilize the planet for hundreds or more years. after the period of the great bombardment ended, life as we know it today formed within a hundred million years, the first common ancestor with it's ~200 genes eventually giving rise to all the diversity of plant and animal species we see today.
basicly, we now have a pretty good understanding of how life first came about on the primordial earth and it seems that emergance of life is inevitable given the right conditions for a sufficient amount of time. since the ingredients for life are pretty commonplace in the universe, it is actually quite ignorant to assume earth is the only planet anywhere to harbor life.

I fully agree with alot of what you posted here. Nicely articulated man [img]graemlins/thumbsup.gif[/img]
BUT
How can we be sure that the so-called 'laws' of physics have always been what they supposedly are now? And if the dynamics of physical forces
can change, how has/does/will that affect the structure of our multiverse?
