Living one's life based on realities that can be observed and/or produce real, observable effects is invariably better than living it based on unrealities such as Santa Clause. Many Christian claims, and ideas found in the Bible, are demonstrably unreal.

You state:"Living one's life based on realities that can be observed and/or produce real, observable effects"
Are'nt you relying on logic? If so where does this logic come from?
