The obsession with exactly two levels

[Angrboda]

The Buddhists don't believe in creator gods. It's all a function of karma which plane you are reborn into after each life, and what sort of being you become. I'd have to do some research regarding Buddhist origins regarding existence and the various planes. My understanding is that in Buddhism, gods are essentially just extremely accomplished and powerful beings. The reason Buddhists likely don't concentrate on the gods is that the goal of Buddhism is nirvana, to be released from perpetual existence. The gods themselves are too comfortable to be motivated towards attaining nirvana, so they are actually considered less likely than a human to achieve nirvana.
