According to them, the stars are all suns. The stars may have the same composition as the sun but they are not suns. The Brahma-samhita says that the sun is the king with unlimited light and temperature. The Srimad-Bhagavatam sublime literature describes all these things and it was written five thousand years ago. And they say that five thousand years ago there was no civilization. That Srimad-Bhagavatam has this information proves that Indian civilization is the oldest civilization.
