The next reply is not to mock you or make you an atheist. I just want to make you think about your reasoning. So don't feel obliged to respond, but please answer those questions for yourself.
1) It seems predicated on the assumption that there is no God, or intelligent designer.
This is completely not true. Evolution does not rule out God. Most Christian churches accept evolution, so it must be compatible?
In fact, almost all of the early work done that lead to our current understanding of evolution was done by religious persons. And that continues today.
Anyway, the theory of evolution explains how all life evolved, but science can never prove (nor will they try) that God did or did not start or guide this process. It should be noted however that everything we understand so far does not need divine action to be explained.
2) The idea that simple organisms can mutate into increasingly complex ones. I'd like to see some evidence this is possible. To think 1-cell organisms can mutate, without a great deal of outside help, into modern humans over a long period of time, is difficult for me to accept.
Is it much easier to accept that an omniscient, omnipotent invisible being always existed or came to existence without cause?
Is the level of evidence you require to accept evolution equal to the level of evidence you require before accepting the existence of God? (Note: Bible contains claims about God, not evidence)
3) That life and intelligence can evolve from a spontaneous action.
You mean life and intelligence...as in...a living and intelligent God?
If evolution can be shown to be consistent with theism, I might be willing to accept it.
Are you saying that you are willing to reject evidence if it doesn't fit in with your current ideas?
Or are you saying you do see (know) much evidence for evolution.
Regardless, as stated before, evolution says nothing about the (non)existence of God. Evolution and God are totally compatible if you so wish.
However, evolution and a literal explanation of the Biblical creation story are not compatible.
And for that subject one could wonder:
- Do I accept the creation claims of a Bronze Age tribe chief, for which no evidence exists (but evidence against it does)?
- Or do I accept the evolution claims by thousands of people who studied that subject for years, and for which mountains of evidence exists, that can be researched by everyone who wishes to do so?
