>fire NEEDS a fuel to burn else it cannot exist
why can the wind exist, why can the earth, and the sky?

where does water come from?
the water eats the eath - why can the earth exist and what does it do ? - if wind blows and water flows, what does the earth do and what does it eat?
what makes the wind blow?
why fire? it is the only one which doesnt do if it cannot eat
