What group of Gods are there?

Answer 1

There are literally hundreds of "Pantheons" (a Greek word meaning a ruling group of Gods) in world history. The vast majority of civilisations have had their own pantheon of Gods to look after their interests, starting way back before written records.

We don't know anything like all the gods that have been believed in, as later religions tend to suppress knowledge of their predecessors. Therefore we only have great detail about very widespread or long-lived religions that couldn't be eradicated in this way for some reason.

These include the gods of...

ancient Egypt (such as Osiris, Ra, Nut)

Ancient Greece (Zeus, Aphrodite, Ares)

Rome (Very similar to Greece, but with different names like Jupiter, Venus or Mars)

Babylon/Assyria (This whole region had a complex intertwining development of religion with gods like Marduk and Ishtar)

Hinduism (Ganesh, Kali, and the like. I'm not well educated on this one)

Scandinavia (Odin/Wotan, Freya, Thor)

Mesoamerica (Quetzalcoatl and others whose names I can neither spell nor pronounce)

Answer 2

There are numerous groups of gods depending on the specific mythology or religion. Some well-known groups include the Greek Olympian gods, the Norse Aesir gods, the Hindu Trimurti gods, and the Egyptian Ennead gods.
