PROMPT:
Create a breathtakingly vivid underwater scene depicting the remnants of an ancient civilization, with crumbling stone structures, ornate pillars, and mysterious artifacts scattered across the seafloor, all teeming with vibrant marine life. Incorporate an enormous, glowing jellyfish hovering above the ruins, its iridescent umbrella-like body radiating a kaleidoscope of colors, from electric blue to emerald green, and sunflower yellow. The atmosphere should be eerily lit, with shafts of sunlight piercing through the water's surface, illuminating the forgotten metropolis. Use a palette that bursts with vibrancy, avoiding pink hues, and aim for a photorealistic aesthetic that transports the viewer to the depths of the ocean.
