Is Our World Real

I have never questioned something like this before. It is very weird to think that everyone you have ever met in your existence is possibly just not real. Scientists are saying that this is actually possible, it could have been going on for years or people from long ago started this. As time goes on for us we are making our games more advanced and real like. With that whose to say that we are not all living that life that they already created making us that game. You are only sure that you, yourself is real because you do not know what everyone is thinking. It could just be you in the world and all of the people around you are just actors and actresses just pretending to be someone in your life. The article said, "What happens, if there is a bug that crashes the entire program." If this philosophy is true than our entire world would crash within minutes. It is scary to think that it is a 50/50 chance. Maybe they will find proof soon but all we know for right now is what each person thinks for themselves. Each person only knows what they are they don't know what everyone else is or thinking.
