I doesn't. I know several scientists who are Muslims...
Also, the RCC rejects young-earth creationism & accepts evolution as fact.
Francis Collins (headed the Human Genome Project & currently the Director of the NIH) is a devout Christian. He also rejects ID as being "not scientifically tenable" and correctly identifies it as what is essentially a god of the gaps issue. From his PBS interview with Tucker Carlson:
Collins: I think intelligent design sets up a god of the gaps kind of scenario. Well, you know, we haven't yet explained this particular feature of evolution, so god must be right there. If science ultimately proves that those gaps aren't gaps, after all, then where is god? We really ought not to ask people to do that.
Carlson: Does evolution even imply that there's no god?
Collins: Of course not. Evolution, although it's called a theory, in science a theory is a collection of observations that are pulled together into a consistent view of things. Electromagnetic theory, for instance. It doesn't mean it's still hypothetical and people don't think it's right. Biology makes almost no sense without evolution to undergird it. Saying as the opening statement did evolution is a theory, not a fact, that's not really quite an adequate explanation of the solidity of information we have

Point being: There's no reason one can't believe in a creator/deity and still accept the fact that evolution happened/happens/is happening.
you might want to look at that research again. the existence of some parts of neanderthal virus dna in some populations does not prove intermingling. current research shows that neanderthals and modern humans did not actually intermingle but a distant ancestor to modern humans may have.
This is not my current understanding, but it's always possible that I'm behind on the topic. Do you have a link to the study/studies that show this?
