So we don't see the sun as of 8 minutes ago, but as of right now?

  From the point of view of the photons, yes. From the point of view of everything else, no. One of the bits of relativity that took me the longest to become aware of was that “right now” isn’t even meaningfully and universally defined within it.

    What about my point of view? He said that if my eyes and the sun are separated by X light seconds, then X seconds later sun and my eyes are at time distance of zero

      This is for an observer following a trajectory in space time. So for an observer covering a distance at light speed the time interval is zero. For other observers on different trajectories, such as stationary in the space coordinates, that will not be the case.
