On topic: "I think so I exist" does not imply that one can only exist if one thinks. P -> Q does not mean !P -> !Q.

For anyone interested: Descartes was discussing the possibility that everything you have ever experienced might be a trick created by some powerful demon (in modern times we might call it the matrix from the movie of the same name). Descartes argues that even if everything is just a trick, if you do not exist, you can not be tricked into believing you do exist. I think, therefore I am.
Re-phrased might read: Because I can think, I must exist in some form (even if I have been tricked about the nature of this form).
