@curiosityontiktok: Flood Mars until water covers 71% of it, and the Red Planet turns into something you'd book a holiday on. That's the same share of ocean Earth has. Same ratio, completely different world. Look at what's left above the water. Two huge green landmasses split by open sea, with giant volcanoes rising out of them like islands built for a fantasy map. Craters become perfect little lagoons. A long, jagged channel cuts deep into the right-hand continent. The dry tan edges still look like a desert. Everything else looks weirdly habitable. A cold, rusty planet, and all it needed was a bit of water to look like home.
