Objects reflect light, but not in the way you think. Light travels, there is no argument here, but if the eyes are a sense organ, they don't see the past. They see the present.
This gets into relativity. When you hear a distant gunshot, the sound of the gunshot to him is gone wen you hear it. When you hear the gunshot the bullet has left the gun barrel.
F0r a supersonic rifle bullet you may hear the bullet whiz past your ear before you hear the gunshot.
A car is going down the road at 60 mph and honks the horn. By the time you hear it the car is not in the potion it was when the horn sounded. To the driver the sound of the horn is in the past, to you it is the present when you hear it.
Someone the Moon pulses a high power visible laser. When yiu see the flash on Eartyh te Moon is not in the same position it was when the laser flashed.
Likewise when we see light from a distant star we see the star as it was was in the past as we perceive it.
We are observing a star and it explodes going supernova. By the time we see it the event event has cone and gone.
When we look at the Sun though a telescope we constant changes. When a flare occurs we see it minutes later, we see the sun as it was minuted in the past for us.
Then there is tie dilation. For people on space station and on Earth clocks run at different speeds. The inference being people age at different rates.
Time dilation is experimentally deom0stred with clocks. GPS does not work without compensating for time dilation.
Past and present are relative to the inertial frame of the observers.
The Earth and the Moon are different inertial frames. From theory and experiment the speed of light is the same in any inertial frame.
My point was visible light LIDAR and radio wave RADAR are the same phenomena. Radio waves and light waves are the same phenomena, act the same, and travel at the same speed.
So, the author's claim that if we see someone talking on the Moon through a telescope we see lips moving instantly before w hear vice sent by radio is false,.
In the day Einstein's relativity showing space-tie was not constant and immutable was revolutionary and Earth shattering in both science and philosophy. He had rock star status.
When he worked on it he was not part of the academic community, his ideas were considered initially as too far out.
