"A prehistoric cave painting depicting a dramatic scene where dinosaurs are being attacked by alien spaceships. The artwork shows large reptilian creatures like T-Rex and Triceratops running away from beams of light coming from hovering spacecrafts in the sky. The cave art style is ancient, with rough, earthy tones and simple, stick-figure-like humans watching in fear. The aliens are depicted as mysterious, otherworldly beings with large heads and glowing eyes, attacking with advanced technology. The painting is set in a rocky cave with faded textures and cracks, making it look thousands of years old.
