In general, the sun is used to warm the planets. Depending on how close each planet is to the sun depends on how life can be supported. On Earth, obviously, life can be supported without all of us burning to a crisp or freezing to death.
The fascinating thing about the sun is while it can provide life, it can also provide death. It kills organisms if they're exposed to the sun for too long, and it can also cause one to go blind if they stare too long.
The sun itself is actually a star, hence why there are many legends surrounding it. Just like all of the constellations, the sun is surrounded by Greek myth. That's why there's the legend of Helios and the sun chariot. Not to be confused with Apollo who was most associated with light...but anyway.
All of the planets rotate around the sun, which is what causes the night and day. Since the planets are also spinning, only one side of the earth faces the sun at a time. It's been in existence for billions of years.
That's the most boring textbook answer one can offer. I prefer the Greek version personally, but you can't ignore fact.
