Not everyone worships every god. Most of them are very minor deities, like the god of a particular river. You might worship that kami if you fish in that river or use it for transportation, but not if you live somewhere else. Likewise, I don’t worship Trump or the Kardashians, but many people do.
We are drowning in gods.
The Japanese worship eight million divine beings. We’ve got about that many too.
Are they actively worshipped as gods though, or are they simply remnants of the past?
