Our Planet Is Dark Because Of The Ocean
Our oceans have an average depth of 12,100 feet. Considering light can only penetrate 330 feet of water, a much more significant percentage of the sea is dark, and anything below 330 feet is in pitch darkness.
Water makes up about 71% of our planet. This means that a vast portion of the earth is dark. You don’t want to get lost beneath the ocean if you are afraid of the dark.
