David Eagleman writes in New Scientist that he is a “possibilian” — a sicentist that doesn’t refute God, like most atheist scientists, nor is he necessarily a religious man.  His article is here, if you want to read it, but rather than coining a new — and inelegant — term, try one that exists…

Agnostic – noun.  1. a person that holds the view that any ultimate reality (as God) is unknown and probably unknowable; broadly: one who is not committed to believing in the existence or nonexistence of God or a god.

Or as I like to put it: atheism requires a certain and commitment I don’t have.
