The sun is the biggest planet in our solar system and the sun keeps on shinning because we need sunshine to live our lives!

It is an Immensly huge ball of hydrogen helium and other materials. Essentialy it's so big that it's own gravity pushes the hydrogen together with intense pressure and heat induceing Nuclear Fusion...the Hydrogen protons combine to form Helium. It doesn't end there the helium also combines with hydrogen and forms lithium and other combinations, although in smaller amounts...
the reson it keeps on going it is just so BIG millions of earths could fit inside so there is plenty of fuel...

It will take about 4 or 5 billion years before the Sun uses up its hydrogen fuel. Then it will start to burn its helium.

Thermonuclear fusion of sunshine (as in 'no longer heavy') atomic nuclei. the warmth and tension (led to by ability of gravity) of a famous individual reasons atoms to overcome the good nuclear tension conserving nuclei at the same time, and fuse. some mass is lost in this fusion, switched over into power. that's the place the equation E=MC(squared) comes into play. Mass encompasses a great quantity of power. A single penny, switched over into organic power, ought to ability your homestead for a life-time. Now, extrapolate that to the mass of the sunlight...

The sun shines because at its center hydrogen is constantly being converted into helium. It does this at a rate of 4,630 tons per SECOND. This process has been going on for at least 4.5-billion years and will almost certainly continue for another 4.5-billion years because of the vast amounts of hydrogen remaining.

Because the sun is given a task by god and the sun just need to do it, no complaint!

Because of nuclear fusion and an 80-billion year supply of hydrogen fuel.

the light from the sun keeps of alive if it was to voyage somewhere else or burn out we will all die

Becasue it has not, as yet, fused all of it's hydrogen fuel into helium.
