Do you have any idea at all how the universe was created? I mean the details. The physical process. Have you spent any time at all looking into it?How do you know God created existence? Is this unsupported statement an example of your logic. Wow, Aristotle must be rolling over in his grave.
Because it is quite spectacular and awe inspiring. All of the matter in the universe being created from nothing occupying the space of a single proton. With 2 billion times the amount of that matter being annihilated in matter / anti-matter collisions converting tremendous quantities of energy into radiation and propelling the matter that makes up our universe outward such that the universe expanded and cooled until such time that it produced beings that know and create and became aware of itself.
All the atoms in your body were created 14 billion years ago through a creative act of God.
