But you didn’t leave it. You went on to reiterate your lack of understanding of the ad hominem fallacy. Do you typically contradict yourself in consecutive sentences?
Here’s an example of ad hominem:
Like an atheist saying “I know there are no gods!” You know this, exactly, how? You have looked everywhere God might be, if he existed, everywhere, and all at once, and haven’t found him? That’s a claim of virtual omniscience, and omnipresence. You really should be worshipped, you supernatural being, you.
Addressed to me. Moreover, it’s a twofer: your ad hominem fallacy was based on a blatant lie.
And a valid analogy can indeed be used in an argument, that’s the main reason for making them, to illustrate and support a point.
The former, not the latter. Analogies are explanatory devices. Your use of the Hoyle analogy tells me that you don’t understand that natural selection is nonrandom.
