Natural language is vague and allows for many possible interpretations of short phrases. The one that is more applicable to Descartes quote is something along the lines of "me thinking proves that I exist". This, of course, says nothing about thoughts being a necessity for existence.

Got it. Now, it makes sense.

Yeah, sorry I missed all of this. I agree that thinking is almost certainly not necessary to exist. I probably could have written it more as "Because I think, I can be certain that I exist"
