You say it created atoms, etc... You fail to explain what caused the "big bang." You don't get explosions from nothing. And explosions don't create life. They don't create anything.
It takes more faith to believe that nonsense than it does to believe in an intelligent designer.
Many now think the big bang was really more like looking up while inside an hourglass.
It wasn't a point of infinite density, but rather an opening from somewhere else.
That's because both trees and blood vessels are fractals. These trees and blood vessels could be created JUST by using a mathematical formulae. Maybe that's how god created the universe, who knows.
