The sun is a star which is made up of mostly hydrogen. The immense gravity of the sun pushes these hydrogen atoms together and because of a process called fusion, they combine and release huge amounts of energy producing light and other types of radiation.
The sun has enough hydrogen to go another 4 billion years.

The `Sun` has 3 layers, the core where nuclear reactions occur. Whereby hydrogen + helium mix at 15 million degrees. It takes 1 million to reach the surface. Our sun is middle age.

the sun is fuel ed by helium gas and has an extremely large quantity of fuel to play with and there for will continue burning for billions of years to come the sun cant just go out because the fuel is a constant source it basically doesn't run out until it dies

Just to let you know everything is ok! Eventually the sun will get hotter to the extent that it will boil the oceans dry ( humans will have perished long before that happens). But fear not, it won't happen for a couple of hundred million years, so go on, smile and relax and be happy when you see that glorious sunshine!

Because of the quantum tunneling of Hydrogen nuclei. Most hydrogen nuclei do not undergo fusion to liberate energy, its only because the sun is so massive that it appears to be very energetic.

Because it's an on-going atomic fusion/fission reaction and, when its fuel runs out in a few billions of years more it will go out.

I guess the same reason why the seas rush to shore. It's not the end of the world I guess.

When it goes every light will go out.I t was set from the beginning of time, just enough to burn throughout time.

Because it has not run out of fuel yet.
