99.9999999% of Your Body Is Empty Space
I will agree that your head is 99.99999% empty space. :-D
So try banging your head into the 99.999999% empty space of the wall a few times. You shouldn't feel it at all! I bet you rationalize a reason to stop banging your head into the wall pretty quick. :-D
If energy has always been with us, it simply changes. Matter is basically frozen energy. So it oscillates between forms. It is still part of reality. Its actions are understood. There is not much mystery. There is no need for the god conjecture.
Atheism is simply a position on the conjecture that there is a god. It has nothing to say about the doom of the world, how we treat nature, or how we treat each other.
