Dr. Francis Collins is doing what religious people do more often than not: Move the goal posts in such a way that their idea of a ‘God’ fits neatly in the gaps. The God of the Gaps. In other words, the usual fallacy of conjuring up a Golem of sorts that is based on nothing other than sophism.
Dr. Francis Collins is a political appointee. Never forget that.
It appears as if you're accusing the ex-atheist (Dr. Collins) of willful ignorance, rather than just being a sincere "learner" in the process of trying to reconcile what he knows about the material world, with what he has been taught (or indoctrinated) about the non-material world.
God knows if he's innocent or guilty in this regard, you don't.
See my previous post above.
