“As I stated, those structures are formed through the process of natural selection.”
Sorry, FRiend...that is simply not possible without an intelligent agent.
Since you are the one making a bald statement of impossibility, what is the maximum level of complexity that can arise without a guiding intelligence?
Large atoms contain quite a bit of "information," yet I doubt that you dispute they can and do arise without a guiding intelligence. So, at what point do you draw the line between acceptable complexity, and complexity that must have come from guiding intelligence?
