The more I look around me, the more I wonder how people can possibly believe in evolution. Is it really that hard to see that it entails believing in the occurrence of an incredible number of improbable events?
Just take, for example, the development of a cardio-vascular system or the eye. Can you even begin to imagine the individual modifications that would be required to get from nothing (or whatever is dreamed up as a precursor) to a working system? Let's say you can. Now start thinking about the probability of each step actually happening - and managing to propagate through the population. Now do it again for all the other subsystems and species. And don't forget to factor in that the fittest don't always survive!
If at the end of all that considering and calculating, you still believe that evolution is a viable theory, I have a bridge I can sell you... okay, not really :>
