Why cant we put anything outside classes ?

Question

i couldnt think about any other title,as i am getting more and more confused.
this is what i know :
an object is "something" which has got some functionality && exists in memory (thats why real-world).
why cant we create objects of "only" methods ?
to be exact,i cant understand why java needs to put everything in the class?
eg.
public static void main(String args[])
int i;
i=i+5;
this method should be able to form an object, it has got both data members, and it can call another function to modify the data.
why do we NECESSARILY need to put this in a class ?

josAH gave a valid point, but are there some others ?Old (current?) PHP is an example of what happens when you have a global namespace. Thousands upon thousands of functions with ugly names or stupid prefixes/suffixes ("real", "2", etc.). Static methods in a non-instantiable class are basically like creating namespaces for global methods.
It's also much easier to find functions that belong together grouped in a class.True, but if "global functions" had been allowed in Java, I bet you a doughnut they would have used package names as a name space, in exactly the same way this is done with classes and interfaces.
But again, idle speculation like this is a waste of time...
