Tell me art doesn't have staying power. What other shit remains from back then? And you know what it is still beautiful 5 to 7,000 years later.
A pigment, a scratch, a line and a surface, no need for any fancy to make art. This is why it's magic, it is so simple at first glance. Art sneaks up on you, you are moved, by a few scratches on a rock.
Tell me you're not moved by this art!
