Life on Other Planets
Śrīla Prabhupāda.  Even on the sun and moon there are living entities. What is the opinion of the scientists?
Dr. Singh , They say there is no life there..
Śrīla Prabhupāda . That is nonsense. There  is  life there.
Dr. Singh.  They say that there is no life on the moon because they did not find any there.
Śrīla Prabhupāda.  Why do they believe  that ? The moon planet is covered with dust, but within that dust the living entities can live. Every atmosphere is suitable for life- any  atmosphere.
Therefore the  Vedas [1] describe the living entities as  sarva-gatah , which means "existing in all circumstances." The living entity is not material. Although encaged in a material body, he is not material. But when we speak of different atmospheres, we refer to different material conditions.
Karandhara.  They say that the moon's atmosphere is unsuitable for life, but all they can legitimately say is that it is unsuitable for life as they know it.
Śrīla Prabhupāda.  The  Vedas  say that the living entity has no connection with material things. He cannot be burned, cut, dried up or moistened. This is discussed in  Bhagavad-gītā .[2]
Dr. Singh.  Scientists extend their knowledge about life on this planet, thinking that it must apply to life on other planets also.
Śrīla Prabhupāda.  Yes. They are thinking foremost of their own selves. They are thinking limitedly, in terms of their own circumstances. This is what we call "Dr. Frog's philosophy. [Laughter.]
Once there was a frog in a well, and when a friend informed him of the existence of the Atlantic Ocean, he asked the friend, "Oh, what is this Atlantic Ocean?"
"It is a vast body of water," his friend replied.
"How vast? Is it twice the size of this well?"
"Oh, no-much, much larger," his friend replied.
"How much larger? Ten times the size?" In this way, the frog went on calculating. But what is the possibility or ever understanding the vastness of the great ocean in this way? Our faculties, our experience, and our powers of speculation are always limited. The speculations of the scientists only give rise to such frog philosophy.
Karandhara.  The basis of what they call "scientific integrity" is that they talk only about what they can directly experience.
