In “Meditation I,” Descartes claims that we cannot trust our senses, why is that?

Descartes discusses the mind and body. Descartes did not believe that the information we receive through our senses is necessarily accurate.He believes that the mind and body are very separate, and the body knows more about the mind than the mind knows about the body. In ways, the mind is in a separate realm of existence, completely separate from body and the Earth on which it lives.
