I think you are struggling with something I thought a lot about too. It is difficult for our brains to actually internalize the /immense/ amount of time evolutionary processes have been happening. It is so long and vast and our brains are barely good with comprehending hours and days. It is a mind bogglingly loooong time. Like really, really, really long. A lot can happen in a few billion years :)
I understand evolution and the time frame. I have no trouble with that concept. What I find difficult to believe is that a viable universe started in the first place to give evolution the opportunity to succeed.
