A million years ago, when hostile natural elements spooked humans and our existence was all about hunting and gathering, the priority of the human mind was survival. The ancient man was yet unaware of the endless potential that lay dormant in his conscience.
One fine day, perhaps while in the search of his food, as it was pouring cats and dogs, the man might have gathered and stacked a few stones and covered them with another stone, and voila! There he had spontaneously created something that ended up protecting him. In that instance he might not have realised that this design would ignite the future course of mankind. Similarly, several more realisations and discoveries followed, that played pivotal roles in shaping the fate of mankind. Gradually, as survival became comparatively easier, the man developed a taste for expression. Walls of his caves became his canvas, and his day to day life became the theme of his art.
