If this is the case, then when we read things like what time sun sets and rises on websites, books, calendars, other official times, et al… does that mean when we see for. How long until the sun gets burned down to the point where it cannot sustain life on earth anymore? The sun would actually look very small to us in the sky if there were no atmosphere (it's the same.

The sun will last, at its current brightness for 9 billion more years.
The sun does not rise, it is the horizon that goes down.
