"It is exciting to think that Little Red Dots may represent the first direct observational evidence of the birth of the most massive black holes in the universe."
We know what will happen to the Sun and our Solar System because we can look outward into the galaxy and examine older Sun-like stars in their evolutionary end states. Nothing lasts forever, including a star's hydrogen. Eventually, stars deplete their hydrogen fuel and leave the main sequence behind. Stars with masses similar to the Sun will first swell and turn red, then shed their outer layers. That's what we see when we gaze at older Sun-like stars.
