Except science can not explain all the facts. It first must dismiss all eyewitness accounts of supernatural events. THEN it can declare that it's explanations are more convincing than everything else.
When you do not exclude such information, then the God of the Christian Bible is the most convincing explanation.
People behaving badly while claiming to adhere to a belief system says nothing about the validity of that belief system. Look at the evidence backing each belief system and then make your decision.
