As we all know there are nine planets and I think life started first in Mercury, Venus, and at present still in EARTH. After completion of Earth's life, Next life begins in Planet MARS (As we all know the Planet Mars is much similar to Earth, this sentense itself indicates that next future LIFE Exists in MARS), and it continues with Jupiter, Saturan, Uranus, Neptune, and Pluto. But it takes n number of years. Any comments, plz mail pran_josh@rediffmail.com
