Existence refers to the state of being or living. It encompasses everything that is real, from the smallest atoms to vast galaxies. When we think about existence, we often ponder our own lives, the world around us, and the universe itself. It raises questions about why we are here and what it means to be alive. In philosophy, existence is a central topic that explores the nature of reality. Different thinkers, like René Descartes and Jean-Paul Sartre, have offered various perspectives on what it means to exist. Ultimately, existence invites us to reflect on our place in the world and the connections we share with others and the universe.
