Morning Scepticism: Gap

I really wonder just what people set out to achieve when they say things like "evolution is God's way of creating life", especially when it's used as a means to inject God at the beginning of the process. With no positive evidence for this claims, it's merely putting God in at a gap in our current knowledge, and for what? Perhaps it's the gamble that science as an enterprise will never be able to account for life through purely natural means, because what happens to God then? Does God become the fine-tuner of constants that allowed for life to arise? If that gets solved by something such as a multiverse, does God become the architect of that? It hardly seems a useful exercise, other than to say "I'm not ready to let go of God yet".
