Nonsense. You've simply tried to set a logical trap and then fashion a reductio ad absurdum from it. Your vapid little exercise doesn't demonstrate that complexity is no evidence of design. You've proved nothing, except that you're unwilling to confront that issue. Go back to your pond.
I can see that the inability to answer the question has made you a bit testy.
Perhaps we'll speak again when you're in a better mood.
