worth noting that Descartes was simply paraphrasing Augustine:

"Again in explicit refutation of the Skeptics of the Academy, he argues that if a person is deceived, then it is certain that he exists. Expressing the point in the first person, as René Descartes (1596–1650) did some 1,200 years later, Augustine says, “If I am deceived, then I exist” (Si fallor, sum).

For avoidance of doubt and clarity of thought:

"I doubt therefore I think [Ed], I think therefore I am"

(Though I always disagreed, saying, even as a child, "You might as well describe any experience or act")
