A bit of Existence

What is the purpose of existence? I believe that the purpose of existence is defined by the one in existence, and beings are defined by their emotions. Likes and dislikes are the output of emotional reaction, and even if something makes sense that does not mean that one will do it unless they are driven by a want or a need, and those are simply output of emotion as well. But we need to live! only because we want to, and we want to because there is an emotional connotation to both life and death. Emotion is everything, and logic is an afterthought that beings in existence invented to try to explain their emotions. I feel, therefore I am. A fox may not think, but it exists. It feels.
So by ascertaining the purpose of existence-a simple amalgamation of emotions that transpire to consolidate their messages-I can assume that I exist, and that so do all other living things. But what about things that are not alive. What about the chair I’m sitting on or the computer I’m writing on. They do not feel. (Or do they…will there be an uprising in the near future? I’m sure Pixar will animate it.) So do objects that are not alive exist? Do the things in your imagination exist? They do not think for themselves, and they do not feel anything you do not want them to feel, but they still exist. So the chair does not feel, and it could be as imagined as the world around us. It could be as imagined as we may be, but everything in an imagination still exists even if it does not take a physical form, so the chair exists. If the chair exists without feeling, then so might I exist without feeling? Yes. So I do not exist because I think, and I do not exist because I feel, I exist because I am.
If the reader disagrees with this, answer how can I not exist? How can you not exist? If this is not existence, then what is? What does not existing feel like?
