That sensory input and beliefs do not constitute knowledge
Descartes famously said "Cogito, ergo sum" or "I think, therefore I am." He argued that even if he was being deceived by an evil demon, the act of doubting his existence still indicated his own existence as a thinking thing. Therefore, the very act of thinking proved his existence.
Descartes aimed to prove that he could establish certain knowledge by doubting everything that could be doubted, ultimately leading to the famous conclusion "I think, therefore I am" as the foundation of his philosophy. He sought to find a firm foundation for knowledge that was beyond doubt.
Descartes aimed to find a secure foundation for knowledge by doubting everything and only accepting beliefs that were indubitable. He wanted to establish a method of doubt that would lead to undeniable truths, ultimately seeking to establish a foundation of knowledge based on reason rather than on mere beliefs or authority.

Rene Descartes philosophy of logic and rationality led him to come to the conclusion that God must exist. Without his existence, there is not explanation for the universe.

By doubting everything that can be doubted, he seeks to find beliefs that cannot be doubted, such as his existence as a thinking being (Cogito, ergo sum).
He gave that name to himself in an attempt to prove to Vin that he was once human.
