Is Spacetime Flat or Curved ?

Many cosmologists believe that '' spacetime is curved ''
====
The spacetime (as whole ) is cold continuum.
The light travels in this continuum in a straight line.
But near the hot masses of stars light can be curved.
Not spacetime curves but the movement of light is curved by hot masses.
#
Sun changes the road of light like a car changes its movement by road
but Euclidian geometry of Earth remains unchanged.
#
Sun (and its surrounded space) curves the straight movement of light quanta,
but the geometry of Pseudo Euclidian (Minkovski ) spacetime remains unchanged.
