Took this to the next level, "I think, therefore i am" but since all you can prove to your mind is that you think, because we couldn't tell if reality was some sort of vivid hallucination, you cannot prove to anyone else that you exist, or that anyone else exists to you. Doesn't mean they don't exist, just unproveable if you allow that everything could be a illusion perpetrated by some sort of demon(i think he was pretty religious so, if someone is duping humanity, it'd be a demon). Which more or less plays into the matrix.
The highest level of doubt is, speaking from self-experience, about your very own existence, the world can come later. Sure Descartes hasn't proven anything out of his mind yet, but that philosophy at least gives you something, however small that may be, firm and unmovable to believe in, yourself.
