Irrelevant as the argument at hand uses logic thus accepts the rules and principles of logic.
No it isn't. It study of reason along with the principles and criteria of valid inference and demonstration
Irrelevant and a point I already made.
Irrelevant. People come up with a different concept of logic not a different logic. If this concept can be shown to work it is accepted. If it can not it is rejected. Hence why people's opinions are not taught as a form of logic nor their opinions on logic.
Even the arguments for design or contingency, both of which are present in this thread, are logic based. Using your excuse I can merely dismiss it because I have a different opinion. This would make me illogical, nothing more.
Logic in this subject is that as other bodies were designed/created, the human body is too. If you want to feel good that it is not, with some excuses of your own understanding of logic or mentioning some philosophies and terminologies, it is your choice. Lifeless seeds grow up to living plants and lifeless eggs hatch to give living animals, with a default similar results for the same species, just like products made of raw material in factories. And even those don't happen point black, but with the presence of some requirements. That's logic. Unless you can actively prove anything can/did clearly become what it is, that is. Otherwise, you can just avoid this by calling it irrelevant too.
