Prabhupāda: Institute, you have got sufficient subject matter as I was describing, this original source of life and the planetary system, as you are going to make planetarium. Who can say about so many planets in the sky? Who has got sufficient knowledge? They cannot even give . . . they think that moon is the nearest planet, but we do not think like that. But still they are unable to give sufficient knowledge about the moon. It is not vacant. It cannot be vacant. We don't find any part of the world vacant. There is living entities. This earth planet is part of the universe, and the moon is also part of the universe. If it is not vacant, how that can be vacant? You have got dust there, here we have got dust—you have got rocks there, here we have got rocks. And why it is vacant? We find in the dust also there is life. When we walk on the beach, it is simply sand, there are so many crabs. They are immediately flying, running, "Oh, here is a man coming. Enter into the hole." So even the dust, in the sand, there is life. So why not there? In the water there is life, within the sand there is life, in the air there is life—everywhere there is life. Why it should be vacant? Hmm? What is the opinion of the scientists? How . . .? We are layman, talking like layman, but why there should not be life? And in the śāstra we get there is life. Not only moon; every planet is full of living entities. Jagat-kīrṇa. There is human being, there is animal, everything. How it can be vacant, God's creation?
Svarūpa Dāmodara: They say they cannot see, so . . .
Prabhupāda: See . . . you cannot see your father; that does not means there is no father who begot you. That is no . . . they cannot see . . . do they say like that?
Svarūpa Dāmodara: They cannot see that, so they cannot prove by experiment, so . . .
Prabhupāda: What experiment?
Svarūpa Dāmodara: Just from experience also.
Ravīndra-svarūpa: They go and look, and that's all they can do. They want to go and see for themselves, so they say they have gone to the moon planet, and they say: "We have not found life."
Prabhupāda: We say you have not gone. I have not seen you, that you have gone there; you say only. How can I believe?
