Prabhupāda: Because the whole world was merged into water. So evolution takes place from aquatics, fish. Then, as the water dries up, there was vegetation, plants. Plants, creepers, trees. Then, gradually, the insects, moths, reptiles, serpents, they come out. And then, from insects, the birds, varieties of birds, and aquatics, 900,000. And eleven hundred thousand, 1,100,000 species of these insects and reptiles. And one million varieties of birds. And then beasts, animals, four-legged, there are three million varieties. So all together this is eight million. Huh? No?
Australian devotee: 400,000.
Prabhupāda: No, total human being, 400,000 species. Altogether, 8,400,000 species of living entities. So these are coming, evolution, by the laws of nature. You cannot stop it. The laws of nature, you cannot interfere. In this way we come to the human form of body, and especially civilized human being. Supposedly, it is the Aryans. The Aryan family, they are the topmost civilized group amongst the living entities. Now, in this life one has to enquire about himself that what is the difference between me and the dog? Why I am claiming a better position than the dog? What is the difference? The difference is that a human being, if he endeavors, he can understand his real constitutional position and he can understand God also. God. Therefore in the human society, civilized human society, there is some sort of religious system. It does not matter whether it is Hindu religion, Muslim religion, Christian religion, or Buddha religion. There is some religion in the civilized human society.
