In debate you need to be able to state your opponent's position befor attacking it. Auto parts do not reproduce themselves and cannot evolve. Try again.
Of course they don't, but it proves the point; even when you have the component parts there is no guarentee they will assemble into the form you want of their own volition.
The same can be said of the "building blocks of life". If you put amino acids, elements, chemicals and such in a bowl, there is no guratenee they will combine to form something we would recognize as life.
I notice you did not defend or attack the other premises about time and incremental steps. Hard to argue with them, is it?
