Extrasolar Planets Suggest that Alien Life is Impossible
These other planetary systems not only show how unique the Earth is but how unique our entire solar system is. Most extra solar planets even those bigger than Jupiter are amazingly close to their stars. One the other hand our Solar System is spread way out over long distances making the orbits are both stable and largely circular. The reason this suggests that ET's do not exist is the planets orbiting other stars tend to be in obits hustle to life.
