So you be saying, that since it takes about 8 minutes before the light from the sun hits earth, there's no way to actually know the current state of the sun at this very moment.

Meaning, the sun exists and it doesn't at the same time, all the time, and we can't ever know which since there always will be a 8 minute time difference.

But if this is the case, then how come there's literally always a sun?
