I suppose people will answer this by asking why would we do that, we’d die!

I’m just going to address the question directly.

The answer is no. We are so tiny. We couldn’t do anything on the scale that would destroy the sun. Have a look yourself. We are not even a pea compared to the sun. We’re just a grain of sand. We could destroy humankind on Earth and wreck our own environment up pretty bad, but there’s nothing we could do that would be bad for the sun.
