Create a 30-second animation in scratch-style pencil art, set in ancient prehistoric times. The scene begins inside a cave with textured walls and flickering firelight. Two early humans—a man and a woman—sit together near a small fire, exchanging a handmade stone tool as a gesture of connection. The animation should include subtle movements: fire flickering, hand gestures, soft expressions, and cave wall drawings glowing faintly in the background. The style should resemble ancient cave illustrations with rough, earthy textures and sepia tones. The mood is warm, emotional, and symbolic of early human bonding.”
