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.
