Detecting design or intent in nature

[Heywood]

You're a shameless liar Heywood, and you should have known I'd already prepared you a short list of just some of the examples you've been offered. Not that you're going to stop this behaviour now that I've posted it, I just wanted you to deny it three times before the cock crowed.

Your body

Is not an evolutionary system.

biological evolution

Chas is assuming his own conclusion. Chas assumes the biological evolutionary system which resulted in his existence didn't require an intellect....so he concludes it didn't require an intellect. Chas wasn't around and certainly isn't privy to the details of how the evolutionary system which resulted in us came into existence. His assumption/conclusion is worthless.

Chinese whispers

Is an evolutionary system that requires the existence of intellect.

Solar systems. Rivers.

Is not an evolutionary system.

Computational systems (and the products of computational systems - such as simulations)

Computational systems which are also evolutionary systems are the products of intellects....at least every computational system I have seen that I am privy to the details of its origins.

-Now go crawl in a hole.

Again I ask you to provide an example of an evolutionary system which you know through observation and not wishful thinking that didn't require an intellect to exist. If evolutionary systems come into being without intellects, this should be easy enough for you to do. If your position is correct, we should be surrounded with evolutionary systems we have observed coming into existence without intellects.....but we arn't. We only observe evolutionary systems coming into existence in conjunction with the existence of intellects. This is reason to believe that all evolutionary systems require intellects.
