The sun is at very large distance from the earth. Assuming sun as spherical, it can be considered as point source situated at infinity. We can treat it like a point object as seen from the surface of earth.

Because of large distance, the radius of wavefront can be considered as large (infinity) and hence, wavefront is almost plane.
