In your last message you said that we onlyy had to explain a few complex systems. Now you've moved the goal posts quite considerably.
So :
1) how many IC systems are there (I'll accept an order-of-magnitude estimate)
2) How many have been explained - and I'll need some explanation of why you think it is that number and no more.
3) How many have to be explained, and why fewer will not do.
Then you can start explaining what you mean by a "large scael" and why you think it hasn't been proven that evolution is capable of acting on it.
As for your argument that systems can't come together - well we've got an example where the evidence says it did happen (the Krebs cycle again). And modification of parts is the name of the game in evolution. That's just one of the flaws in relying on Behe's mousetrap analogy as any sort of guide.
For the last sentence, if ID's explanation is "God did it" with no further explanation then ID is not science - it's theology and not very good theology at that. And since the ID mvoement won't even admit that ID *is* "God did it" - they're more likely to issue angry denails at the very suggestion - it really isn't a valid defence.
