Relating to or characterized by opposition to atheism and the assertion of religious or theistic beliefs.
From 'anti-' (against) + 'atheistic,' from Greek 'a-' (without) + 'theos' (God). The adjectival form describes positions or arguments countering atheism.
An antiatheistic argument might be 'look at how complex the universe is, so God must exist'—it's not just saying you believe, but actively using reasoning against the atheist position!
