Isn’t pantheism the same thing as atheism?

[Alan V]

Per Google: "God: 1. (in Christianity and other monotheistic religions) the creator and ruler of the universe and source of all moral authority; the supreme being.  2. (in certain other religions) a superhuman being or spirit worshiped as having power over nature or human fortunes; a deity.

There is no "standard" definition of God.

Of course there are standard definitions. I just offered two for "God" as well as several for "Pantheism". Look them up.

However, if by this you mean people have all sorts of additional attributes they include in their God-concepts, that is most certainly true. But "God" is a family-resemblance term that requires a certain number of shared characteristics, even if it is entirely imaginary, like a vampire.
