Functionally identical ? I don't think so. If I believe in a creator that would imply purpose to the creation (you and I). different world view = different behaviors ?

I appreciate your comment.

An unknown/unknowable god (like "the big bang" or the gods in Prometheus or Spinoza's god) does NOT "imply purpose" (this would be the teleological fallacy).

DEISM informs nothing about human morality or meaningfulness.
