Because rock is not water dude. Look up the difference between solids and liquids.
That explanation doesn't make a bit of sense. You claim light will warm a solid even if it only barely penetrates it, but it won't warm a liquid that it barely penetrates. But you don't say why. You just declare there's some magical difference between solids and liquids which makes it true, even though it makes no sense, and then you demand that everyone else BELIEVE in the magic too.
Normal people, OTOH, point out that light warms any object that it is absorbed by. Solid or liquid, deep or shallow, it doesn't matter. It's simple conservation of energy. The energy contained in the light has to go somewhere, and that somewhere is heating the object.
