Well, to avoid derailing:
1. Apparent structure does not neccesitate design.
2. The developement of intelligence does not imply intent to develop intelligence.
Nowhere do I ever rule out the possibility that there is a creation deliberate or not to the universe.
What I ask is , if there is deliberate design to the universe, what structures that have arisen would show that. From what i can see there is solely contingent history, the developement of intelligence seems more acausal than causal.
Hypothesise that there are other intelligences that have arisen in the past and are currently present perhaps. In which case tyhey have ben randomly destroyed by meteors and the like, or they are currently being driven to extinction.
I agree that there maybe a 'watch maker' universe, but if so the watchmaker has little concerns for what happens after the winding of the watch.
So I see no privilege or exception that would indicate a deigned universe. Otherwise, would we really be so free to kill other intelligences, like dolphins and whales, which might be closer to 'god/designer' than us?
