Ancient Egyptians just called it all the underworld and never bothered with the details, they didn't like claiming to know too much. Though they did have one belief that I liked, it explains a lot about reincarnation and other such beliefs. They have the Ba and Ka of the person, the Ba is your spirit and goes to the underworld (if Anpu allows you to based on how guilty you are) and the Ka moves on to enlighten another spirit with your wisdom and knowledge. Kind of a cool reason why humans kept getting smarter each generation.
What's different about the teachings on the six realms is that there are two ways of viewing them.
On one level, there is the idea that the realms are 'real' 'places' to which one 'goes to'. That's called the teaching as 'skillful means'. It is skillful if it motivates you to work on your mind and heart and uproot the five poisons.
Then there is the wisdom level of the teaching of the realms, which is more subtle. These are not held to exist, except in a dreamlike way--including human existence.
