Humans may actually be fish because we have gills inside our body that work like a filter, just like real fish.
Imagine you're drinking water from a glass, but instead of just swallowing, your body takes in the water and turns it into something useful. That’s what gills do! Fish use gills to take oxygen out of water so they can breathe. We have something similar inside our bodies that helps us process oxygen when we drink or eat, kind of like having a tiny, invisible filter inside us.
How It Works Like Something You Know
Think about how you clean your hands with soap and water. Your skin helps you feel things, just like fish use their gills to help them breathe underwater. We might not look like fish, but our bodies work in a way that’s very similar, we’re kind of water-friendly inside!
So even though we walk on land and eat food from plates, the way we take in oxygen is pretty much the same as how real fish do it, just hidden inside us!
