  It is shown in this paper that the geometrically structureless spacetime
manifold is converted instantaneously to a curved one, the Riemannian or may be
a Finslerian spacetime with an associated Riemannian spacetime, on the
appearance of quantum Weyl spinors dependent only on time in that background
flat manifold and having the sympleic property in the abstract space of
spinors. The scenario depicts simultaneous emergence of the gravity in accord
with general relativity and quantum mechanics.The emergent gravity leads to the
generalized uncertainty principle, which in turn, ushers in discrete space
time. The emerged space time is specified here as to be Finslerian and the
field equation in that space time has been obtained from the classical one due
to the arising quantized space and time. From this field equation we find the
quantum field equation for highly massive (of the Planck order) spinors in the
associated Riemannian space of the Finsler space, which is in fact, the
background FRW space time of the universe.These highly massive spinors provide
the mass distribution complying Einstein equivalence principle. All these
occurred in the indivisible minimum time considered as zero time or
spontaneity.
