1. Why there is no life on other planets!

2. order for life to exist on other planets, there obviously has to be "other planets." Currently, we haven’t seen any other planets outside our solar system. I am sure they are out there (probably most stars have some type of orbiting bodies), but our current visual telescopes are far too limited to see these distant objects. The only reason we can even see stars is because they are gigantic floodlights blasting a tremendous amount of light in our direction. Planets, on the other hand, are very small and don’t produce their own light; they only reflect the light of their sun.

3. Public opinion has swung to extremes on this issue. In 1600, the Italian philosopher, Giordano Bruno was burned at the stakes because he maintained the "heretical" notion that there were countless other worlds out there containing life. In the 18th century, the pendulum shifted to the other extreme; many astronomers were convinced that every star had planets with life. Will Herschel (the man who discovered Uranus), even speculated that the sun was populated with life.

4. The Earth seen from the surface of the Moon Earth is a perfect distance from the sun, or else the earth would be too hot for life. Earth has plenty of water for humans, something other planets lack. We have proper living conditions, for both humans an animals. We got lucky enough to get all of this once, I don’t think it could be like that somewhere else.
