There is no absolute — everything is relative. The relationship between each and every person/object is unique but fundamental to the persons/objects. Without others, one is nothing. Relationships construct the world as we know.
It is irrelevant what we think of as a unit object, be it a person, object, or molecule, but it is indivisible. Suppose that the universe has nothing but one unit object. It sees nothing, and therefore does not receive input from others, in terms of physical properties. No force, light, or energy is applied to the unit object. It is thus dead, as it does not produce any output. Therefore, it is non-existent since it has no purpose, function, or relationship with anything else.
This is based on the assumption that the object is indivisible. Is anything ever indivisible though? Sure the quarks inside electrons may seem like the building blocks of life, but they are divisible. But since everything can be divided, it is never possible to isolate one indivisible element, as it does not exist. Logically, this disproves my theory of relativity since very small objects interact. Interesting, no?
Makes sense, but too sciencey for me. :D
