Not currently known, there is no experimental support for the graviton at this time. On the other hand, General Relativity (which does not postulate gravitons) is a successful theory.
 
A better question would be why would a graviton particle theory be accepted. There is no direct evidence for gravitational waves, much less gravitons, so why would their existence be accepted?
 
Well, since Quantum Field Theories were really effiecient in describing the other 3 interactions, people hope it can be used for gravitation as well, that's why graviton is hoped to exist.

Postulating the existence of such a particle will also give Newton's 1/r law in the classical limit(just like GR), which is a good thing, but... There are problems with incorporating gravitons to the Standard Model of praticle physics, so this is kind of one frontier of theoretical(and mathematical) physics...

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
