I think what you're saying is that because God created life billions of years ago, and we can't, God is better than us at molecular biology.
If we last another 6 billion years we probably will succeed in creating new life. We've made tremendous progress in just the 50-ish years since the Miller-Urey experiments, which created 22 kinds of amino acids from primitive swamp gas and lightning. We haven't succeeded in causing life to emerge yet, but we can produce all kinds of precursors. If we have 120 million times as long to try, I think we'll get there.
As for the initial life that evolved into us, it needn't have been created at all. The very fact that we're finding it so difficult to do deliberately suggests that it happens more easily as a natural process. The Earth is vast, the chemical ingredients it provides are diverse and plentiful and they had billions of years to mix. The sheer number of possible combinations is staggeringly large. The odds against one of those combinations resulting in life? Not so large.
