Evolution is a fact, but not all the details are understood. That not all the details are understood does not falsify the fact that organisms evolve and change over time in response to environmental conditions.
That Abiogenesis is not understood does not falsify the fact that organisms evolve and change. It just means that Abiogenesis has not been worked out yet.
There is no evidence for the 'Hand of God' at work in the natural process of evolution.
