If life can be created in the laboratory, then there is no question of doubt that life would have arisen spontaneously from the ooze that was the early planet earth billions of years ago. No need for a God, just spontaneous generation of life.
Too bad for all you Christian Fundamentalists.
Billions of years later, with the process of evolution constantly in play we arrive at the world as we know it today. Again, no need for a God. Again, too bad for the Fundamentalists.
Consider also the unfathonable size of the universe with billions upon billions of galaxies like our own Milky Way and the possibility of life emerging on another planet is extremely high.
The most complex of all variables is that life would evolve in any way similar to life on earth. Why should it?
Not all planets would have similar environments as earth to allow for evolution to follow the same path from single cell organism to multi-celled complex organism. In other words, alien life forms would most likely be unrecognizable as life to us.
And finally, the possibility of intelligent life evolving that would be anything like intelligent life on earth is not a foregone conclusion.In fact, according the the Drake equation it's very unlikely.
The Drake equation states that:
- N = the number of civilizations in our galaxy with which communication might be possible;
- R* = the average rate of star formation per year in our galaxy
- fp = the fraction of those stars that have planets
- ne = the average number of planets that can potentially support life per star that has planets
- fℓ = the fraction of the above that actually go on to develop life at some point
- fi = the fraction of the above that actually go on to develop intelligent life
- fc = the fraction of civilizations that develop a technology that releases detectable signs of their existence into space
- L = the length of time such civilizations release detectable signals into space.
