The cosmological argument for creation from nothing

Hello Rabbi,
One of the foundations of the claustrophobic/cosmological argument as presented by William Craig is that nothing can come from nothing.
But I wanted to ask if this is really so? After all, free choice is itself the creation of something out of nothing. If so, we have refuted the assumption of the cosmological argument. [And if you say that the creation of choice is not out of nothing, then this is determinism in disguise].
 
With great respect,
Moses
