I'm a student 10 years (or so, maybe 8) under the tutelage of a physicist whose specialty is God v. Naturalism. His 67 video curriculum matches his book: God, Science & Mind: The Irrationality of Naturalism. I transcribed nearly all of his videos and I typewrote his entire book including the footnotes.
If you really want to know.
If spiritual longings evolved in the same way as our desires for food, drink, sex and knowledge, how could those longings be incapable of fulfilment? Imagine two genetic lines, one of which spends significant time and resources searching for mucta, which does not exist, and another like it in all respects except for the mucta-drive. Cleary, the second line will out-compete the first. For such evolutionary competition, we need the two variants, each able to pass its mucta-desire trait on to its heirs.
If we take mucta to be God, the naturalist hypothesis points to the demise of spirituality. Is this hypothesis viable? There are atheists who profess no spiritual longings, and they tend to pass their position on to their children. So, while the preconditions for the evolutionary demise of spirituality exist, theists are not an extinct variant, but the majority of the population. So, spirituality is adaptive. Its adaptiveness is confirmed by the correlation of spiritual behavior with health, psychological well-being and longevity.7 Thus, if evolutionary psychology correctly accounts for the development of behavior, including spiritual behavior, it is hard to see how the quest for God could be baseless. At the very least, naturalists attacking religion and spirituality are working to reduce human fitness.

I only had to remember one word "mucta." But he talks about little else throughout his book, 1000 authoritative case references, more with the videos, and each one of those science books has maybe 100 references.
Love to me is more important than science, or I guess I would say, "Love and science must be joined at the hip for maximum existential penetration."
