The major energy currency molecule of the cell, ATP, and its relationship with melanin in the context of creationism are analyzed. These complex molecules are critical for all life from the simplest to the most complex. They are two of millions of enormously intricate nanomachines that need to have been designed in order for life to exist on earth. ATP is an excellent example of irreducible complexity because it is necessary in its entity in order for even the simplest form of life to survive. Without ATP, life as we understand it could not exist. How did life exist before ATP?
