This is something I am very interested in.
It is important to distinguish that evolution is the explanation of how life arose from simplicity to complexity. It is NOT the explanation of the ORIGIN of life, that field of study is called abiogenesis which proposes that for life to occur there must first be a self replicating molecule that can carry information - once that is achieved, evolution takes over and explains how we came to be today. How and when this happened is still unknown, but it is a field of study that I believe will eventually answer the ORIGIN of life.
Perhaps it is God, perhaps not - but surely we should not assume the former and forego future discovery?
