Is there life on other planets?
The Vedas tell us that life exists everywhere in creation. Scientists looking for life on other planets may never find it, because their criteria for life-supporting environments are too restrictive. Life, being spiritual, doesn’t depend on a certain mix of chemicals. The soul, or the life force, can exist within subtle forms imperceptible to scientific instruments. (We have some experience of this at night, when we exist in a subtle dream world.)
The total material energy contains many universes, which float in a relatively small space in the unlimited spiritual sky. Each universe is shaped like an egg, the shell being made up of seven elemental layers, each ten times thicker than the previous one, beginning from the innermost.
Each universe contains millions of planets, situated within fourteen systems, with earth in the middle region. The planets above the earth are realms of heavenly pleasure and are reached by souls who properly execute their religious duties as human beings on earth. The lower planets are places of darkness and are the destination of materialistic persons who reject the guidance of revealed scriptures.
The Vedas state the earth is the best place for spiritual advancement because it is relatively free of the extreme happiness or suffering found on other planets, making it suitable for focusing on spiritual thoughts.
