As far as we know those planets are devoid of life. Whereas the earth has been teaming with life for billions of years. During that time the earth has gone through thousands of extinction events with 6 mass extinctions (when upwards of 90% of all life went extinct).
Our success (humans/mammals) is the result of one of those extinctions. So yeah, life has a strong foot hold on earth and it will continue to do so long after we're gone.
