Finally an atheist proper, with views and questions

[Lucian]

Sound enough.  We'll not soon run short of examples showing how we're built to find dinner, not the truth.  OTOH, we'll also have plenty of examples to show how and why accurate observations and predictions make you better at finding dinner.  How the apparatus of seeking one particular dinner-based truth might have multi-use potential.  

The trouble, really, is that it's a disingenuous argument.  A person who assumes the truth of evolutionary processes in a criticism of their product as truth machines has already declined to endorse their own fundamental objection in at least one case.  They're having or purporting to have a rational conversation with you as though it would be probative and accurate.

Could you expand on that bit about declining to endorse their own fundamental objection? I am not sure I quite get what you mean (never claimed to be clever)
I like to try to meet people where they are with their arguments when possible. The “ok, here are your premises, you believe that our cognitive abilities are good enough that this can disprove naturalism, however I think our cognitive abilities are bad enough that it is strong evidence for naturalism or a bad designer, or a disinterested deist god”
