Atheism and the existence of peanut butter

[R00tKiT]

God, through the laws of physics. 

And, so, God long, long ago decided what decay products would be emitted from which U238 atoms and when those emissions would occur?  If so, how about an atom bomb?  The upper limit is about 25% efficiency, Fat Man & Little Boy being well below those yields.  Did God decide which U235 atoms would participate in those explosions and which would not?

Well, God purportedly gave room for free will and things like that... He surely dictates the rules (natural laws) but there is no reason to invoke God's intervention in the various human events. And clearly, Project Manhattan is responsible for Little Boy, not the deity.
