Question: is there any other planet which have life on it or any oxygen or light or anything found till now.? 

Answer: No planet other than Earth has been positively shown to have life on it yet.  Other places in our solar system have conditions that are comparable to conditions in harsh environments on Earth.  These harsh Earth environments do contain a variety of simple life forms, such as hot vents on the ocean floors, antarctica, etc.  This makes planetary scientists think that it is likely that simple organisms will be found elsewhere in the solar system soon.\n\nThe short answer: Almost, but not quite yet!
