According to Emile Borel, a French scientist and expert in the area of probability, an event on the cosmic level with a probability of less than 1 out of 10, to the 50th power, will not happen. The probability of producing one human cell by chance is 10, to the 119,000 power. Also, Fred Hoyle has calculated that the probability of a SINGLE MOLECULE of DNA coming into existance by chance is 1 in 10 to the 40,000 power.DustTrailFinder wrote: I think it's entirely possible that elementary organic molecules came from beyond earth and accumulated both within it and on its surface. There is ample evidence that organic molecules exist on comets. It's also possible that some organic molecules were created on earth through natural processes on earth itself. At this moment in time no one can be absolutely certain how life began, nor can they be certain where it started. All we do know is that on earth, you and I do exist and that records exist that tend to show how we and other animals evolved over time from previous living organisms.
This would also invalidate the theory that life originated on another planet and travelled through space to get here. Like I stated before, if something is a physical and mathematical impossibility here, taking the question to somewhere in space wouldn't change anything: if it is mathematically impossible here, it would also be impossible anywhere else.
I could give many more evidences against evolution, but I guess I've been going on long enough.
