All depictions of gods by humans are whatever interpretation humans come up with. It's no coincidence that most gods look like humans for the most part, with the occasional animal part mixed in: humans view themselves as the most important thing in the universe, so gods they envision share a form that aligns with that. Usually you only see real creativity with the servants of the gods - things like "biblically accurate" angels or what have you.
Even if you wanted to make the argument "well gods can manifest in whatever form they want, so people can't be blamed for depicting them in a way they allegedly depict themselves to mankind", that just supports the idea that their true form isn't how they manifest themselves to people and if a god is manifesting themselves in a specific form to better interact with humans, then the form they take is fluid, picked to accomplish a specific goal, and could range anywhere from an old dude with a beard to something that looks like a fire elemental made of lava and obsidian or whatever the fuck they felt would be fitting at the moment.
