Matrix or simulation?

Are we all plugged into The Matrix at 'birth'? Oblivious to our womb-like liquid filled pods in some dark, dystopian future?

Or do we just exist in some gigantic computer simulation created for the amusement of some super intelligent alien civilisation?

Probably we are just who we are. That there is nothing mysterious out there. We are just born, live and die in some gigantic universe oblivious to us and with no consciousness of its own.
