If lights is extremely fast and manages to get to the Sun to the Earth without getting darker. How come light can’t bounce off everything and manage to get into every crevice of Earth. Why are there shadows and why do they vary in shade? They should logically be the same shade right?

It does, pretty much. Few places are truly devoid of all light. A shadow is an area with less light, not no light otherwise objects in shadow would be invisible. Light can still strike objects in shadow by bouncing off of other objects.
