rocks do not reflect enough light to be visible in what is otherwise total darkness. until you can provide an example of that, i will stick to my statement.
Duh. Rocks wont reflect
any light in total darkness because there's no light to reflect. That's why it's called
total darkness.
We can see the part of the Moon lit up by the Sun even when the Sun's not visible from our part of the Earth the same way we can see things lit up by a streetlight even when you can't see the streetlight itself because something (like a house, or a tree) is in the way; the whole scene doesn't suddenly go dark the moment we step into a shadow. The Moon is a quarter million miles away; it can be dark where you are while Mr. Moon is still in direct sunlight.
Maybe why you're getting confused is because when it's dark your eyes are much more sensitive to light, so the same Moon that was barely visible in the day seems very bright at night.
i have never once used a youtube video as evidence.
Good thing; they're seldom to never very useful.
