Moles are necessary to solve problems of stoichiometry. We cannot calculate chemical equations based strictly on mass, as formulas change from reactant to product. Using moles gives us a method of "bean counting" that allows us to balance equations and mass, thereby obeying the Law of Conservation of Mass.

Actuallly, it just a convenient unit instead of having like 100000000000 billion atoms we jsut have a few moles it makes the numbers more managable cause one mole equals a whole hell of alot of atoms.

because the size of the things being talked about are so small that it takes many many many many of them to make up any sort of measureable amount. So instead of saying "a trillion trillion trillion trillion trillion atoms makes up one gram of calcium, we say 3.5 moles of calcium atoms make up 1 gram".

why is it necessary to have any unit? so that things are compared on the same scale worldwide...

Because measuring individual atoms would be extremely tedious without it.
