How do I know you're real? You can say you're real, but how can I tell you're real, and not just some mind game played by some Penultimate Being?
See, that's how you shoot down Cogito Ergo Sum.
Actually that is precisely the line of reasoning that led DeCartes to his conclusion that the only thing he couldn't doubt was his own existence in some form or another.
"Real" is an entirely subjective thing. You can not be a "real" person, but all the same can still be a "real" existence outside your own conception, and that's as "real" as the life you thought you had. What is the actual definition of "real"?
