According to astrology (Jyotisha), there are nine planets (Graha). Brahma created many planets and among all planets, He made only earth (Prithvi) livable for humans. He established life only on earth, not on any other planet. I want to know why only the current planet is chosen for human beings? Is there any related story or reason described in scriptures?
Note that I'm not talking about Lokas, I'm talking about planets i,e Grahas.
