A Theory on Reality

Hello.

I recently listened to an RT Podcast over at roosterteeth.com where it was mentioned by one of the hosts the idea of the Matrix. Except that it was centered around him rather than the human race.

In essence he questioned the concept of reality. To explain his supposed argument I want you to pick up an object near you. Give a brief description of the object you now hold. This object is real correct?

Now imagine or look back to an event from before your own birth. Describe the event to the best of your ability. This is also real correct? Prove it. Prove that that happened to someone who is either younger or the same age as you. Prove that WWII happened. Prove any event, preceding you, has happened. Prove that any physical account is not simply an artistic creation and that all personal/professional accounts have not been falsified. Prove that everything that you have been taught that you don't have personal experience with, Is. Not. A. Lie.

Not to sound pessimistic but the idea that you can't be certain  if something happened or existed then what can you believe.
