Vasil Vus :
Gotta agree that the Christian creator’s "spiky knives" analogy was a pretty bad caricature of Plantinga’s EAAN, but your response still misses the actual philosophical problem:
First, you’re treating survival and truth as the same thing. Evolution only selects for actions that keep you alive, not whether your mental beliefs are actually true - it rewards fitness payoffs, not ontological truth. Even if you argue that survival requires reliable local mapping to navigate the environment, that only applies to basic physical threats. It does zero work to guarantee that our brains are reliable for abstract metaphysical claims.
Second, saying "I don’t assume my brain is reliable, I check it against reality" is textbook circular reasoning. What are you checking reality with? The exact same brain, logic, and senses whose reliability is in question! And before the "well, theists are circular too" objection: there’s a massive difference between unavoidable foundational trust and holding a worldview that gives you an active, self-generated defeater. If your origin story says your cognitive tool wasn’t built for truth, using that tool to declare itself reliable is a total logical loop.
Third, you literally pointed out that our brains are riddled with cognitive biases and are terrible at abstract logic and probability. You argued that we need science and logic as "scaffolding" to correct our flawed brains. Sure, science corrects local empirical errors. But science is a methodological tool - it doesn't prove metaphysical naturalism. The leap from "science works" to "only physical nature exists" is an abstract philosophical conclusion made by that same evolved brain. If our brains are that bad at abstract thinking, why trust them when they conclude that metaphysical naturalism is true? Naturalism is a massive abstract claim, not a basic survival instinct.
EAAN doesn’t claim naturalism is false or that truth never helps survival. It shows that unguided evolution gives the naturalist an inescapable global defeater. If your worldview is true, you have no rational ground to believe it’s true.
