“Why do evolutionists trust their own minds?”
If we didn’t, it’d be mighty tricking to decide what’s for dinner, now, wouldn’t it?
“When creationists point out the glory of God's design haven't you heard them pick and choose examples of what they consider "bad design".”
Yes. Earth biology reflects a ‘trial and error’ approach, not a perfect plan.
"But as they believe no God and believe in evolution this would show that evolution produces bad design.”
When compared to what is claimed to be a perfect designer, yes. But there are degrees of badness between ‘perfect’ and ‘useless.’ We seem to be suboptimal, not useless.
“That could include their own brain”
Feel free to actually show a systemic problem with the human brain that prevents the development of important theories, then.
Careful, though, if the human brain is flawed, yours is flawed as well as ours.
"which could be very flawed and require mutations to improve until it is adequate to comment on how it got there.”
If that were true, you could probably show it rather than just appeal to ‘maybe’ like this.
“So, I don't see how evolutionists can trust their own minds”
Airplanes. We figured out airplanes with these brains. Seems like a useful sumcheck.
“or seriously convince anybody else that anyone else can trust their own minds”
IF you don’t want to trust YOUR mind because it MIGHT be flawed, that’s your choice. Just don’t pretend it’s a convincing argument without any evidence.
"or indeed if they themselves have adequate minds to make such a decision.”
And again, if you’re going to assert that my, or anyone else’s brain is flawed, we need evidence for that. Not the fact that the spine is poorly designed for upright standing.
