Existence itself is not typically considered an entity in the conventional sense. Rather, it is a concept that refers to the state or fact of being. It is a fundamental aspect of reality that encompasses all things that exist or have the potential to exist.
Entities, on the other hand, are generally understood as individual beings or objects with distinct attributes, characteristics, or identities. They can be concrete, such as a person, an animal, or a physical object, or they can be abstract, such as a concept, a belief, or a mathematical theorem.
While existence forms the backdrop against which entities come into being and interact, it is not itself a discrete entity. It is more akin to a fundamental quality or condition that allows entities to exist and be experienced. In this sense, existence can be seen as a foundational aspect of reality rather than an entity in its own right.
