In the movie Patton, an aide consoles the general upon learning that Rommel was not present in North Africa for the tank battle. "If you defeated Rommel's plan, then you defeated Rommel." If evolution defeats God's plan known as intelligent design can we apply the same logic to conclude that for evangelical believers at least their God is "defeated". Can we use the triumph of evolution as evidence that God does not exist since intelligent design is presented as His work?

Defeating Rommel's plan amounted to defeating Rommel because there was something Rommel was trying to accomplish and defeating his plan kept him from doing that. Stopping someone from carrying out their plans is a straightforward case of defeating someone. But evolution isn't something that stops God from doing what he was trying to do and so it doesn't "defeat" God. If we can show that evolution is true, we've defeated a view about God, but God isn't a view.

In fact, however, I think your question really is the one in your last sentence: does showing that evolution is true show that there's no God? The answer is somewhat controversial, but I'd say no. It shows that a particular view of God is not true, but it doesn't show that there's no God. There are plenty of believers who think that evolution is true and that nonetheless, there's a God. Maybe no reasonable notion of God can be consistent with evolution, but this isn't nearly as obvious as it's sometimes assumed to be.*

* Of course, showing that evolution is consistent with belief in God is one thing; showing that there's a God is another.
