Why Btonze Age?

[CapnAwesome]

I don't get how Iron age or Bronze age makes a difference? Could you explain their case a little more?

It pretty much boils down to weaponry. As is often the case with humanity. Iron gave you a literal edge over bronze. So Iron had an advantage. Not only in war, but also in terms of agriculture.

Duh. But how is that an argument for the Christian's making the case that it reinforces the bible or a case against Atheism? That's what I'm asking.
