Sorry but I didnt mean to sound unsubjective. Its just very hard for me to accept that billions of mutations would result in anything but failure for a living organism.
For example. Lets say you have a single celled organism (one of the very first) but its immune system hasnt evolved yet. All it would take to wipe out each and every living cell would be a paper cut and then youre back to square one. There would be millions of similar "weaknesses" for the early life forms.
That being said. What percentage of the mutations are beneficial? How many mutations would it take to produce the reproductive system? Wouldnt the addition of the reproductive system cause potential harm to the mother? Then by natural selection all of those carrying the reproduction traits would die off. Now you have no reproductive system and you have to start all over. It would take billions if not trillions of organisms to allow for the process of natural selection to work without killing all of them off. There are too many processes that have to be just right.
The millions of steps that have to be exact for the process to function at all is the over complexity that I see. 5 billion years is not enough time.
I agree that it may be possible for a cat to evolve into a lion, but not for an ameba to evolve into a human. Once life has been established with a large population to work with, natural selection is feasable. But to start with the first cell and to have it grow and multiply, that is very difficult. The process of creating life would have tremendous odds aganst it.
Im just saying that IN MY OPINION the whole theory of abiogenesis, and to a lesser degree evolution, is at best very very difficult to naturally occur and have posotive results. Its like a plant that you dont water or fertalize or give enough sunlight to. It usually dies. Why would the very first life forms be any different?
When I referred to evolution as chance I mean chance mutations that ultimately result in progress. Like chance when throwing dice. Have you ever been to Las Vegas? Did you go home with more money or less?
