What is real?

Have you ever wondered if this life we have is reeal? Or is it just something our mind has created to keep us busy? To entertain us? I'm not sure what the truth is behind everything but what can be real. We are taught what to think, how to act, what to do, what to be. Lets face it we are taught everything by people who are taught by people who were taught by people. What can be the truth and what isn't? How did people come to realize what space is and what plants are and how to speak and eat and everything. We are things living in a thing that is a thing. Confusing right? But no one has any ideas what we are or why. ONLY THEORIES. That's what this is as well as theory. People say they have evidence to prove this and evidence to prove that but in all rights what is evidence? Where does it come from how can it proved? They say we have been to space and there is a bunch of nothingness and planets and gravity. But then what. after all the planets, stars, and nothingness, what comes after that? Darkness? There has to be something? Are we like fleas on a dog moving from one dog to the next and living there all our lives but having no ideas what is beyond the dogs we live breed and eat on? So my theory on this is anything that people don't understand someone comes up with a theory or an idea to prevent chaos. See I believe that the human race is run on fear everyone uses it. When something can't be understood there is a theory or idea put in place to calm the masses and keep them under control. The governments and religions worldwide do a fine job of this. But now the chaos is slowly building due to everyone and everything only cares about money. No more values and one community beliefs. The masses fall apart people rebel and it turns to chaos. Aka- a lot of wars break out and more religions and governments form trying to calm everything back down but mainly make as much money as possible. Thus causing even more chaos and problems. but back to the original thought. What if this world isn't real our mind has created this as a dream and you are in a coma or some sort of thing and none of this and nobody is real? What if you wake up and everything and everyone is 100% different? Or what if some of it is real but the rest isn't like the people are real but space or air or plants aren't?

Just a thought.
