Clearly there are some explanations which are worse than no explanations at all. Yet humans don’t seem comfortable living with the unaccountable. We even talk of things themselves demanding an explanation, when really it is us doing the demanding. Perhaps then we crave explanations, and this craving sometimes leads us to accept things we really have no good reason to.
How else do you explain the rhetorical force of asking how else you explain something? Asking a question like this shifts the onus from the claim-maker to the person accepting or rejecting the claim. Instead of having to provide evidence or arguments to defend her position, the claim-maker is demanding that the person assessing her view either offers a better explanation or shuts up. But this shifting of onus is unreasonable. If you offer an explanation, it is up to you to show that it is a good one, not for me to show I have a better one. My rejection of your explanation does not require that I have a better one to hand. In the same way, if someone writes a terrible poem, it’s no defence for them to argue that you couldn’t write a better one.
