There is a God
We cannot deny the fact that the perfect organization and order of all the bodies in the universe is caused by a Great Designer. Try to bombard something, does it make a harmonious arrangement and placement of its scattered and dashes parts?
The Entropy and Negentropy in our universe keep our existence in place. The gravitational forces which with just a single digit alteration will cause our habitation to collapse.
We tend to base our beliefs and perception in the physical senses we have. But there are more, which the five major senses could not perceive.
Faith is something which cannot be accepted by those who do not acknowledge the supremacy of the Great Designer of the universe. But faith is not to have a perfect knowledge of all things yet hoping for something which is true.
God is not evil. All these tribulations, deaths, and suffering are just existent here; where the physical senses of man is dominant. Death is not the end, if it is, then the science's law of conservation of energy and mass would be null and void.
Allah, El, God, or whatever label or name it is, He is the cause of everything's existence. Proof is not needed if it is existing.
God is a God of Mercy and Justice. God is a God of life and Death; God is the God of the Heavens, of the Earth, and of the Hell; God is the God of the angels, of the humans, and of the devil's, and of Satan; for God is the God of everything.
