"Therefore, even though we don’t have a perfect theory of physics, we can say that we understand certain stuff quite well." Sure I agree to that. "And vague statements about life and “new ideas” don’t help us advance our understanding." But I disagree that we understand it well enough to exclude subatomic life with certainty. So vague questions like the one here in this thread certainly won't push the field. It is more about a principle of being open to me and explore the idea a bit with different minds. Because I know enough history of arrogant science thinking they know it all already. I suppose you are aware of Max Planck? That his Professor tried to discourage him from taking up physics as it is all already well understood and not much remains be found and understood? Statements from your sibling poster reminded me of that.
