According to Descartes if it is clear and distinct it is real
Descartes engaged in the program of radical doubt to establish a foundation of knowledge that was certain and indubitable. By doubting everything that could be doubted, he sought to build a system of beliefs on a solid, unshakable foundation. This process ultimately led him to his famous conclusion, "Cogito, ergo sum" ("I think, therefore I am").
Descartes' doubt is often associated with his method of radical skepticism, which posits that doubt should be applied to all beliefs that can be doubted in order to reach certain knowledge. This led to the development of the famous phrase "Cogito, ergo sum" (I think, therefore I am) as a foundational certainty. Descartes' doubt also influenced the development of epistemological theories, such as foundationalism and coherentism, which seek to address the issue of how certain knowledge can be attained in the face of doubt.
Descartes' method of systematic doubt has been widely influential in philosophy and science. It has helped to lay the groundwork for modern epistemology by emphasizing the importance of skepticism and rational inquiry. However, its success can be debated, as some critics argue that aspects of Descartes' method are overly radical or unrealistic.
Descartes decided to set aside everything he had learned in order to systematically doubt the foundations of his knowledge and beliefs. By starting from a point of radical doubt, he sought to build a new foundation for knowledge that was certain and indubitable, leading to his famous statement "I think, therefore I am."
René Descartes famously stated "Cogito, ergo sum" or "I think, therefore I am." This idea encapsulates his philosophical skepticism, suggesting that everything should be doubted until proven by reason. Descartes sought to establish a foundation of knowledge that was beyond doubt through his method of radical doubt and skepticism.

Short answer: Descartes' doubt was like WWI - the doubt to end all doubt. Only by doubting everything could Descartes hope to find anything that was certain (even if the only certainty is that nothing else is certain!).
Descartes found it impossible to doubt his own existence. The reason for this was that he felt that thoughts had to come from himself.

Descartes cannot doubt his own existence, as captured in his famous statement "Cogito, ergo sum" - "I think, therefore I am."
He can not doubt that he thinks, therefore he exists.
In Descartes' Meditations, doubt serves as a tool for philosophical inquiry by challenging and ultimately casting skepticism on the reliability of sense perceptions and beliefs. Through methodical doubt, Descartes aims to uncover indubitable truths and establish a foundation of certain knowledge upon which to build his philosophical system. Doubt, therefore, acts as a catalyst for Descartes' quest for certainty and the establishment of foundational principles in his philosophy.
René Descartes, a French philosopher, created the system of systematic doubt. In his work "Meditations on First Philosophy," Descartes employs the method of doubt to question all his beliefs in order to find a foundation of certainty in knowledge.
Descartes creates the evil genius in an attempt to throw everything that he thinks he knows into question. The evil genius has god-like power that he uses to deceive Descartes. Descartes cannot disprove the existence of such a creature. You cannot trust your thoughts in such a scenario, thus Descartes cannot be certain that any of the information he gets from his senses, his memories, his thoughts, or his beliefs is real.
