You may not acknowledge evidence that rational intent exists as an aspect of nature, but other people observe organisms and internal organs responding intelligently and purposefully and regard those observations as evidence of the reality of purposeful intent.
Okay, I won't even ask you to define "rational intent". However, for this assertion to be even worth considering, I would ask you to provide one single actual example from nature where we see "organisms and organs responding intelligently and purposefully". If you can, then we can consider your example in context. At the moment, all we have is your assertion that such things take place.
