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?

If you thought about your question a bit, why isn’t the moon as bright as the sun since it is reflecting the sun’s light?
Therefore somewhere your reasoning must be incorrect. Also if every object reflected ALL the light that hit it, then everything on earth you see should be as bright as the sun?
Since this is not true, it therefore means that not all light is reflected.
Also think about something like a candle, if brightness (intensity) does not decrease with distance, then a candle would look equally bright from 1 feet away as it would look like 100 ft away – is this your experience? So if you think it doesn’t hold true for a candle, why do you believe the sun is different? Light intensity decreases with distance and you experience this all the time.
