text: why only the earth has life on it?   greetings...  life could actually be abundant in the universe but for now only the earth is known to harbor life and thats because of pure luck or could be due to devine intervention... the earth just happen to be on the right spot and at the right time... not to close (we could burn)or too far (we could freeze) from the sun and not to close or too far from the center of the gelaxy where a blackhole is said to exist and it is also a dense place full of stars and dusts which could threaten life... we sure are lucky because if we are not there's no way you could be here to ask that question in the first place and i couldn't have answered it...
