Atheism vs. God's Existence

[AAA]

Because he can't answer why there are design flaws in an intelligently designed organism, especially considering his intelligent agent is allegedly perfect. He'll whitwash over them, belittle them and ignore them, but he can't explain them.

Not that it's a real explanation, but I suppose the approved Christian answer is "sin". What else can he say, since he refuses to assess the state of nature outside his religious bubble?

I think of three reasons that there is "poor" design. 1: The claimed poor design is the result of a damaged system (cancer, and almost all diseases involving a damaged genetic code). 2: Things are optimally designed. In other words, why can't you design a boat that is the fastest, largest, and most buoyant ship possible? It's because in order to make the fastest ship, you would have to minimize unneeded space, which would by definition keep it from being the largest ship. (I think this is the case with the esophagus). 3: We simply don't understand its function yet (I think this is the case with the RUBISCO enzyme and its photorespiration).
