Every atmosphere is suitable for life- any atmosphere. Therefore the Veda's describe the living entities as sarvagatah which means "existing in all circumstances". The living entity is not a material. Although encagedin a material body, he is not material. But when we speak of different atmospheres, therefore we refer to different material conditions. They say that the moon's atmosphere is unsuitable for life,but all they can legitimately say is that it is unsuitable for life asthey know it. 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 Gita. Scientists extend their knowledge about life on this planet, thinking that it must apply to life on other planets also. 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 ina well, and when a friend inform 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.
