Who decides what is property? It’s the people who claim ownership. At one-time, African-Americans were considered property. What gave those people the right to do that?
Under current law, domestic animals are considered as property. Who gave us that right? Many people point to the Bible, which says God let man rule over his creation. If I were to create something and tell you to take care of it, that does not make it your property.
Man can create things like houses, furniture, machines, etc., but only God can create life.
