TL;DR: What can be asserted without evidence, can be dismissed without evidence.
Belief, unbelief, disbelief, contrary belief – they’re all on a continuous scale. And one can hold any position on that scale for any reason. As for me, I tend to be on the side of “strong atheism” (I don’t really like the term, but I don’t have any good alternatives), with the following reasoning: I have not seen, heard, read, experienced or otherwise been presented with any convincing arguments or empirical evidence of a concrete kind in favour of the existence of supernatural beings (or the supernatural effects in general). Claims of the existence of supernatural gods(1) are such extraordinary claims that I will require extraordinary evidence to believe them, and as such, I see no good reason to assume they might be there. Until we get concrete objective evidence in favour of their existence, I consider the existence of gods to be quite irrelevant for me [Edit: in the way I live my life]. Also, I consider musings into the probabilities of hypothetical gods, goblins, trolls(2), nisse, mermaids, etc. to be quite futile.(3) and I act and live my life like there are no gods or supernatural phenomena. Thus, I see no reason to assume the possible existence of such beings or phenomena. However, if any evidence of a convincing nature in favour of the existence of a god/gods should pop up, I will reconsider. But until then: nopety-nope.
Edited to add: The above does not preclude me from arguing against supernatural stuff and in favour of naturalistic explanations. My background in physics and the sciences shine through here.
(1) as opposed to humans or animals that were/are treated like gods, like kings of the past, Hitler, Stalin, the Kim klan of North Korea, etc.
(2) apart from internet trolls, which are demonstrably real.
(3) Caveat: fictional stories, fairy tales, and mythology are OK as fun and games, for entertainment and for understanding historical contexts and cultures of the past. But not for serious consideration of any truth claims. However, myths like told in e.g. the Iliad, about possible historical events spiced up with interpretations of divine interference for dramatic effects, can have been spun around a kernel of real historical events (minus the divine stuff, of course).
