Do Presuppositionalists suggest that because everyone presupposes God they all know God exists (what about the Trinitarian God)? (I'm also trying to keep in mind Romans 1:19-20). My question of the presuppositions people make is at the level of their knowledge of doing so. For example, morality. Does presupposing God for morality mean that one really knows God, or can we say that one borrows from the Christian worldview without knowing it?
