If the sun were to supernova, why would we not be able to see it before it kills us, even though nothing travels faster than the speed of causality?

Question

Since nothing travels faster than the speed of causality/speed of light, why is it said that if the sun were to explode we would not know, or see it, until we died?

Answer 1

Because the enormous amounts of heat, light, UV, and x-rays will kill you. It’s not the “blast” of the explosion, it’s the EM radiation it emits that will kill you instantly.
