I think this points out something undeniable about reality.
In some way it makes “no sense” to think that human beings must come into existence via some peculiar process of cell development and then emerge through the birth canal of existing female humans. That, too, “makes no sense” in that there is no obvious reason why THAT should be way of things instead of some other. Why should gravity instead of laws of repulsion be the way of things? There is something, at ground, nonsensical, arbitrary and capricious about why anything is the way it is instead of some other.
Now, an atheist will simply acknowledge that that is simply the way of things, the “brute facts” of existence and deride the theist for wishing to have a further explanation. It seems to me, despite the claims of people like Peter Atkins, this resort to brute facts is the determinably “lazy” strategy.
A theist could, despite claiming God did it, still posit that God has discoverable “reasons” for having done so, whereas by resorting to “brute facts” the atheist is proposing a terminus to all inquiry of his own determination.
Even if the ultimate reasons behind birthing or biogenesis make “no sense” to us in terms of our current understanding and may not, in fact, have completely “logically causal” reasons for being one way rather than another, it does not entail God having his reasons could not at some point provide the fully comprehensible story.
Even if we discover that a madman committed a crime, the madman could have nonsensical reasons, albeit still “reasons” for having done so. The atheist, as per this analogy, is simply left with the brute inexplicable facts and believes those to be sufficient. The atheist isn’t willing to accept any “crime” was committed because of a presumption that there is no possibility of it being ascribed to any intention whatsoever, no matter how nonsensical, but that just having occurred ultimately suffices to account for every possible event in its every detail, in spite of the fact that, in the end, such an explanation is no explanation at all since it, ultimately explains nothing since it leaves all subsequent “explanations” ungrounded.
