Each every planet has got different atmosphere. And each and every planet, they're different kinds of living entities just suitable for that atmosphere. Don't think that in the sun planet there is no life. There is also life. If there is no life, how Kṛṣṇa says that imaṁ vivasvate yogaṁ proktavān aham avyayam (BG 4.1)? Vivasvate means . . . the king of sun planet is known as Vivasvān. So Kṛṣṇa spoke with him, so how you can say there is no life? This is material world, many millions of universes. In another place it is said, yasyaika-niśvasita-kālam athāvalambya jīvanti loma-bilajā jagad-aṇḍa-nāthāḥ (Bs. 5.48).
So we have to take information from the authoritative literature what is the position of this material world, the spiritual world, God and His relationship with us, our position. This is real knowledge, not that a knowledge that how to live. Living condition is fulfilled by the nature's way. There are 8,400,000 different forms of living entities. They are not concerned how to eat, how to sleep. They know, by nature's arrangement there is already arrangement. Just like the birds in the morning. They rise up early in the morning. They are not concerned where they will eat. They know there is already arrangement for eating. The elephants in Africa, they know that God has already arranged for their eating forty kilos at a time. The ants within the room, they are . . . they know there is already arrangement. So if God has arranged for everyone, eight million different species of life or forms of life, why not for human being? There is arrangement. But in the human being is advised to do certain things. They must do it. Then there is no question of scarcity. There is . . . everything is arranged there. Just like Kṛṣṇa says, annād bhavanti bhūtāni (BG 3.14): "You produce your food grains so that the animals and the man, both will be happy." But if you don't produce food grains, if you produce sugarcane, then how they will be satisfied? Food grains must be produced. That is the injunction of the śāstra.
