Timeline – Stone Age The sun has risen few hours back. A primitive man walks out of his cave. He is dressed in animal skin and is seen yawning after a long slumber. He breathes out and smells his breath against his palm. He grunts at the foul smell.  He rubs his eyes and walks to the nearest babul tree, breaks the bark of the tree and chews it between his teeth. He scowls at the strange taste and again smells his breath. He is not satisfied with the result.
