Naming particles

Let's assume two electrons are moving in a certain direction. They have the same velocity. And they travel in the same detection(velocity have direction). Then they travel together.Say one is in left and the other in right. So how do you know that, one is in left and other in right. Well it is because of existent of an observer. Observer first identify electron A and B, and continually track the path of each electron. If there is no observer you will not be able to identify which is A and which is B. How died the observer track the electrons. He will compare the change of the electron comparing to it's surroundings, the environment. Since both electron is identical to the other, it is not possible to identify it like you identify John, the person.

A new theory: an unnamed object is a wave. When it is possible to name an object it becomes a particle. Naming is possible only when observer is present. Observer is not a live individual or a machine like a computer, it is the environment. Position of a particle depends on its environment.
