英文小作文：

What is existence?

Existence is a fundamental concept that we all deal with every day, whether we realize it or not. We exist in a world full of people, things, and experiences that shape our lives and make us who we are. But what does it mean to exist?

For some, existence is about surviving and making it through each day, while for others, it is about exploring and understanding the world around us. Existence can also be about seeking meaning and purpose in life, or about finding happiness in the simple things.

However we define it, existence is a powerful force that shapes our thoughts, actions, and emotions. It is something that we all have to deal with, whether we like it or not. And while there may be times when we feel lost or alone in this world, there is always the possibility of finding meaning and purpose in our existence, no matter what challenges we face.
