ADDING TO THIS POST FOR FURTHER CLARIFICATION: It isn't that light doesn't get reflected off the object. It's that we wouldn't see the object if that object's reflection weren't already at the eye. This reflection has nothing to do with the speed of light because the light is not what we're interpreting.OK.No, you're missing the concept entirely.No, it moves in straight lines at c. Water flows.Light flows.Obviously, if two premises contradict each other, something is wrong, but nothing in his proof has contradicted itself.
P1: Light takes time to get to the eye.
P2: Light is at the eye instantly.

That's nonsense. Reflected light is at the reflecting object, in the instant of its reflection, and then takes time to travel from there to the eye.The only thing that is at the eye instantly is the light that is reflected onto our photoreceptors.
At which instant, the light is "at the object", right?Light is reflected off the object.
You're still not getting it. If we can see the object, the light has to be at the eye. There is no gap.Well, there must be time involved, because light "at the object" is not also "at the eye" (given that the object is not "at the eye"). So time is required for the light to get from "at the object" to "at the eye".There is no time involved when looking at the object because light has to be at the retina in this version of sight or we would not be able to see said object. It's the necessary condition to see anything at all.
If the light is at the object in that instant when it is reflected off the object, then it is NOT at the eye at that instant.
Of course we can. It doesn't mean that light doesn't travel. It's just that we wouldn't see the object if light were not already at the eye.And "because light has to be at the retina in this version of sight or we would not be able to see said object", we therefore cannot see instantly.
Light travels; therefore, you have concluded that what we see cannot be instantaneous, but that's not correct when seen from a different perspective.This is unavoidable from what you yourself just said.
There is no contradiction. Light travels, and we see in real time.That not only does not follow from what you wrote; It is directly opposed to what you wrote. It's not a "summary"; It's a contradiction of what you just finished saying.So, to summarize, there is absolutely no gap between the object seen and the light because time is not involved, even though light travels.
