OK, so I think we're actually back to where we started. You're setting up a false dichotomy between so-called "pure randomness" (whatever that means) and some sort of rationality that you've decided is God. I haven't said and wouldn't say that the universe is like a "shuffle playlist." And honestly, throughout this whole conversation I haven't seen you do anything more than argue by definition and play word games.
I'm also disappointed that you refuse to conclude the previous thing we were discussing before moving on to this new thing—I'm not interested in just switching subjects without finishing them. I don't think you should feel like you HAVE to have an answer, but you should acknowledge when you don't (and I should do the same).
In answer to this post, let me reiterate: I don't care whether something is mechanistic or random or rational or what. Those are just words. Reality is what it is, and we have cognitive faculties that allow us to make incredibly precise predictions about it. If we launch a ball into space at a particular velocity, we can know its precise trajectory as long as we know the masses and velocities of the objects around it. And if we're not sure our assumptions are true, we can toss the ball out and see what happens. Truth isn't some substance -- it's a word we use to describe ideas with strong predictive value. If we doubt our rationality (and I think this is a very good thing to do), we test our predictions and see if reality supports them or not. That's how science works, and that's why I think science is better than religion.
Given that we seem to be going in circles at this point, I think it's time for our conversation to draw to a close. You've given me a lot to think about and I've enjoyed talking to you, so I thank you for your time.
