The other day I was talking on the morning walk about the sun globe. They say because it is fiery there cannot be any life there, but sometimes we see a big iron factory is full of flames from the chimney at a long distance, but does it mean there is no life in the factory? Fire is one of the five material elements, and Bhagavad-gita says that the soul is never burnt by fire. So in the sunglobe globe if the living entities have a fiery body, just as fish have body suitable for living in the water, so how is it that there is no living entity in the sun globe if they have a body suitable to live in the sun globe? In the Vedic literatures it is said that there are germs (agni pok) within the fire.
