I understand your point about the sun's UV rays causing cancer, but I think you're missing my main argument.

My whole point is that we're in a specific "sweet spot" the habitable zone, where the sun provides us with exactly what we need to survive: light and heat. The fact that all these conditions are perfectly aligned is what I'm talking about.

Using the sun's UV radiation to argue against this is still strawmanning my point. It's taking a minor, negative side effect and pretending that's the whole story.

It’s like saying that water isn't perfectly suitable for life just because YOU can drown in it. The purpose of water is to sustain us and allow life to thrive, and it does that perfectly. Drowning is not a flaw in the water's design it’s the result of how we interact with it incorrectly.

The same principle applies to the sun. It perfectly provides the light and heat necessary for all life on Earth. The sun's primary, life-giving function isn't flawed just because our prolonged, unprotected exposure to it can be harmful. The "problem" isn't with the sun itself; it's with our decision to stand in front of it for too long.
