Discovered in Cueva de las Manos in Santa Cruz, Argentina.
As you can see from this ancient cave painting dating back who knows how many thousands of years, even at the beginning of civilization the human mind craved creative expression and immortality.
Was this due purely to some dastardly mutations of the DNA, a spontaneous sizzle of electrical sparks in a developing cortex, an inspiration from a loving God who chose to reveal himself, or a combination of similar random spiritual and physical events?
Probably none of the above, but rather some other reason that we will never understand.
