i am honest in agreeing that a simple structure opens the possibility of a designer.
you, however are dishonest in disagreeing that a more complex structure greatly increases the chances of a designer.
given that anyone with half a brain understands this concept. it can only be intellectual dishonesty on your part to find it more likely that the more complex structure has NO designer.
now go run and hide.
I think he's having issues understanding your intent behind the metaphor. What Bushidogrendel (at least how I'm reading it) is saying is that if you have a shack (us humans) and you also have a mansion (a more complicated structure/being - eg. God) then it is more applicable to question who the creator of the mansion is than the shack, as it would be easier to comprehend that the shack happened by chance than the mansion appearing by chance. Now where he's applying this metaphor is that it is easier to comprehend humans happen to be without something/someone creating it than it is that a God just happened to be, thus the conversation doesn't end with God created man, because who created God?

P.S. I apologize if I butchered your metaphor. That's just how I read into it and felt maybe having him hear it through different words may clear things up. Please speak up if this wasn't the intent of your metaphor as I don't want to impose my bastardized view of it and will wholeheartedly retract this post.
