Look, that is a possible view. Some philosophers have argued for it. But that doesn't mean it's very plausible, or that it's worth taking very seriously. I am the only thing which exists. Time does not exist.
Nothing ever changes.
No people exist, including me. I do not exist, and you do not exist. Numbers do not exist. Numbers do exist, in fact they are the only things which exist. When you come across crazy views like these, I hope you will have your guard up.
