Why do you think we live on this planet?

Bullocks. You mean what is the point of life? It's kinda crazy how everyone wants look so impressive and do what everyone else is doing. I guess you can do something you think is important and even that may change. Maybe you search your whole life why everything is the way it is or why you are here. Look up Existentialism or Absurdism, but don't think too hard or you'll feel horrible.
