Light doesn’t really have a direction.
It only appears to have a direction in time.
From the point of view of the photon, it exists as an atomic emission, immediately hits its target, and is reabsorbed.
So there is no back for it to come from.

From the perspective of light, time itself doesn’t exist, so speed doesn’t exist.
