I tend toward the Occam’s razor philosophy. If something is too complicated to explain, it’s probably not true. On the other hand, Jared Diamond showed how primitive religions have to be complicated in order to act as an identity challenge for strangers to a tribe. In that sense, trying to understand heaven is like trying to understand a cryptography key, rather than any actual message. Moses decoded all of the essential wisdom. Since then, it’s probably been just marketing. There’s plenty of ways to be useful to this Eden without buying and selling imaginary worlds. Unfortunately, the worse our personal world looks, the more attracted we are to the imaginary ones.
