Apparently before the beginning was the void. Then eons ago for no knowable reason there was a "big bang" and nature began conceiving and filling the void with life. One conception was humanity. Over time nature guided the evolution of our predecessors up to the level of realized potential mental capacity that enabled 'Eve' to ask 'Adam', "Why am I?", the small bang that gave birth to humanity.
When 'Eve' picked the 'rose' 'Adam' saw white emptiness and having an instinctive fear of the unknown he tried to fill the void. He passed his effort on to succeeding generations and we may pass it on for "Why am I?" can't be answered. It will be "the last why".
To the extent we try to fill the void we restrict nature's effort. Nature's effort is natural, white. Our tries are unnatural, black. We blend complementary amounts of both thus by choice humanity is a shade of grey between self-creation and self-destruction. It is obvious we are dark. We can't replant the 'rose' but we can empty the void, set nature free and return to the light.
