Today I learned about Rene Descartes and his help in modern philosophy. I also learned about some of his most famous words "cogito ergo sum" I think therefore, I am. This also concludes that my questions today are; Do you exist? How do you know you exist? Why do you think your existence matters?  I know that I exist because everything grows and is alive not a hologram or a piece of plastic. I think my existence as for right now does not matter because I am just a person like  any other regular person of my age. If I work hard enough then I can make my existence really matter as someone such as an inventor, entertainer,actor or anyone as long as I work hard.
