Are there any people on any other planets besides Earth?

That is the big question! No one really knows if there are other people on other planets, intelligent life forms. In our lifetime, only the moon has been briefly visited a few times - no planets in our solar system have been physically visited by people. The distances to other solar systems is huge, 4.2 years of travelling at the speed of light just to the closest one. Maybe one day we will have the technology to go to other systems to see if there are any other people out there. Until then, we will never know.
