What If Humans Evolved Underwater?

If humans had evolved underwater, our physiology and society would be drastically different. We would have adaptations such as gills for extracting oxygen from water, webbed fingers and toes for swimming, and possibly thicker skin to withstand water pressure. Our homes and cities would be built on the ocean floor or within underwater caves, utilizing bioluminescent organisms for light. Communication might rely more on visual signals and body language, as sound travels differently underwater. Our diet would primarily consist of marine life, and agriculture would focus on cultivating seaweeds and other aquatic plants. The concept of fire and traditional metallurgy would be absent, leading to alternative technological developments using materials like coral and shells. This underwater existence would profoundly influence our culture, myths, and understanding of the world, centering around the ocean and its mysteries.
