Not to mention the how a lot of polytheistic gods (like the greek pantheon for instance) were made up of total crazy psychos, lol. And while, yeah, the gods could intervene on your behalf and you could make offerings to them, really what you wanted if you were smart was for the gods not to notice you and leave you the hell alone, because more often than not, their interference in your life made things worse. And people still worshiped them.

Also not all religions have the concept of heaven and hell or a reward in the afterlife either. Even the greeks who sort of had a concept of an afterlife (which came late to their oral tradition), it wasn't something that was generally fun - in the best case scenario, you were a shadow of yourself walking endlessly in the Elysium fields. So I could see people worshiping this sort of absentee, disinterested god. It doesn't seem any odder than a lot of other religious traditions out there.
