I disagree. As I mentioned earlier, a god is an object of human worship. I think this means that if something is not worshipped by humans, it is not a god.
Even if a thing would be worshipped as a god once a human being found out about it, it would not be a god until that worship happened.
An analogy: say there was a boulder that, thanks to the natural effects of erosion and whatnot, was just the right shape for someone to sit on. Is that boulder a chair? No, not until someone assigns it to that purpose.
... but what do you think makes a god a god, then?
