IF there was no fire in the sun how do you explain setting someone's oily hair on fire by rays from the sun using a suitably focused magnifying glass?

Heat without fire happens all the time. Heat is focused to the point of ignition then you have fire. Not so different from rubbing two sticks together. Concentrated heat.

Oxygen, fuel and heat are needed for fire to occur. This is known as the fire triangle. Combustion is when fuel reacts with oxygen to release heat energy. ... Combustion that results in a flame is very fast and is called burning. Combustion can only occur between gases.
"Combustion is when fuel reacts with oxygen to release heat energy" and "Combustion can only occur between gases." sounds contradictory when we know the fuel can be gasoline. It must be the wording methink.
I think the sun is a great big hot thing somewhere out in space.... It give life and warmth to every living thing on this planet and also lights up our lives on a daily basis plus allows us to have one free trip around the universe for free each year..... I think that just about explains it in p laymen terms....:)D
And for those who don't understand why he is kidding:
The Sun can "burn" hydrogen to helium without the need for oxygen. It should be noted that in the presence of carbon, nitrogen and oxygen, stars heavier than the Sun may burn hydrogen to helium by using the C, N and O as catalysts. Even in these stars, however, an absence of oxygen does not prevent nuclear burning.
