Modern scientists attempt excursions to other planets, but they have no information of how many different types of oceans and seas there are within t… - A. C. Bhaktivedanta Swami Prabhupada

We understand in the sun planet also there are varieties of living entities, but their bodies are made of fire. As our body is made of earth, similarly, their bodies are made of fire. There are five elements in the material nature: earth, water, fire, air, and ether. So in different planets, there are different atmospheres and different bodies also. Don't think that each and every planet of the same quality. No. Same quality in the sense because these five elements are present there. Without these five elements, no material thing exists. So somewhere the fire is prominent. Somewhere the air is prominent. Somewhere water is prominent. Somewhere earth is prominent. So in this planet, or in some other earthly planet, earth is predominant. Similarly, there are other planets also. So don't think that other planets are vacant. No.

When one's relationship with the Supreme Lord is established, the next program is to act in that relationship. This is called abhidheya, or activity in relationship with the Lord. After executing such prescribed duties, when one attains the highest goal of life, love of Godhead, he achieves prayojana-siddhi, or the fulfillment of his human mission.

It is understood from this verse that the predominating deity of the Moon is the maintainer of all the trees and plants throughout the universe. It is due to the moonshine that trees and plants grow very luxuriantly. Therefore how can we accept the so-called scientists whose Moon expeditions have informed us that there are no trees or vegetation on the Moon? Srila Visvanatha Cakravarti Thakura says, somo vrksadhisthata sa eva vrksanam raja: Soma, the predominating deity of the Moon, is the king of all vegetation. How can we believe that the maintainer of vegetation has no vegetation on his own planet?
