Svarūpa Dāmodara: The age of the rocks, by determining by scientific techniques, find how old the rock (indistinct) is, and how correct it is. So I asked (indistinct) of this department, Professor Roland, and he told me that (indistinct) such and such, I mean the rocks coming from the moon, brought by astronauts. They calculate that by this (indistinct) technique, they find that they are about three to fourteen million years old, these rocks from the moon, the moon samples. But that does not give the real age of the rocks. He told me that what you call the age means how long that crystal... For example they tried to find out the crystals like iridium and strontium crystals, that the method that they use is strontium iridium technique and so he told me that the age, this age, about three times three billion years old, that means that crystal containing that iridium model has crystallized for that long year, that gives the age. They do not know how long it has been there
Śyāmasundara: The rock is at least three billion years; maybe it's older.
Svarūpa Dāmodara: Yes, maybe older, but it does not give the exact age. We do not know.
Śyāmasundara: But the point is that they have determined that there are rock structures in the earth very, very, very, very old and that these contain no evidence of any complex forms of life. So that if there is a statement that there were higher forms of life millions of years ago existing on this planet, there has been no evidence ever found of that.
Prabhupāda: So why they're trying to find out evidence from the rocks, not from any other source?
Śyāmasundara: Well as civilizations come and go, they leave remains, evidence behind of their...
Prabhupāda: "Civilization goes" means? Where goes?
Śyāmasundara: Well, if people come and they...
