Our solar system is just one specific planetary system—a star with planets orbiting around it. Our planetary system is the only one officially called “solar system,” but astronomers have discovered more than 3,200 other stars with planets orbiting them in our galaxy. That’s just how many we’ve found so far.
Our Sun is just one of about 200 billion stars in our galaxy. That gives scientists plenty of places to hunt for exoplanets, or planets outside our solar system. But our capabilities have only recently progressed to the point where astronomers can actually find such planets.
There are an endless number of galaxies in the ever expanding universe.
DO YOU REALLY THINK we're alone?!?
Do you REALLY believe WE, Earthlings, have ANY REAL CLUE about an afterlife?!??
Use common sense, people.
