There are many thinkers who ponder questions about life. These thinkers who ponder questions about life are often called philosophers.
The Greek philosopher who said "I think, therefore I am" was René Descartes, a French philosopher and mathematician. This statement is more commonly associated with Descartes' philosophy rather than Greek philosophers.
Medieval philosophers and scientists typically studied theology, as well. This was considered to be the final authority on all matters.

Many philosophers and scientists disagreed with René Descartes, most notably Thomas Hobbes, who criticized Descartes' dualism and emphasized materialism. Additionally, empiricists like John Locke and David Hume challenged Descartes' rationalism, arguing that knowledge derives from sensory experience rather than innate ideas. Other critiques came from later philosophers such as Immanuel Kant, who sought to reconcile empiricism and rationalism while questioning Descartes' notions of certainty and the self.
Descartes' questioning of what it means to be human, how we can escape solipsm, explain the self and believe in God had a large effect because it caused many following philosophers to consider the same issue. For example the philosoper Hume came up with many criticisms of Descartes, namely what exactly is 'I' in 'I think therefore I am.'
Some of the most well-known French philosophers include René Descartes, Jean-Jacques Rousseau, Michel Foucault, and Simone de Beauvoir. These philosophers have made significant contributions to various fields such as metaphysics, political philosophy, and existentialism.
Descartes was a student of all the philosophers and mathematicians who had preceded him. Every great thinker builds on what has come before. Beyond that, he thought about interesting unanswered questions and tried to come up with answers.
Some very famous philosophers are Socrates, Plato, Aristotle, Confucius, Descartes, Nietzsche, and many, many more.
Descartes' conclusion is "Cogito, ergo sum" which means "I think, therefore I am." This statement reflects his foundational belief that self-awareness and consciousness are inseparable from existence.
