Im not saying mysteries automatically make beliefs logical. But if take the universe for example, its complexity still astonishes people, and to this date scientists themselves can conclude that it was simply nature taking its course, or if it is something more profound (such as a creator), such discourse allows for the belief of God. After all, if you werent sure if a certain sports team lets say The New york giants beat the dallas cowboys. It still leaves me room to assume the dallas cowboys won the match, the only conclusion is we both arent certain who won, but either side can still be correct. Thats logically okay.
