You have the opportunity in Worlds Builder to build the world from scratch the way you want to see it, and first you need to create an island among the vast expanses of water. Then, forcing the forces of nature to interact, plant the island with greenery, create mountains, grow bushes and trees, plant plankton. A violent reaction will begin, evolution will rush by leaps and bounds and a man will appear. Build a primitive hut for him. It should work and produce something, so you need a quarry, a sawmill. And then pottery, carpentry and other industries. Develop trade, technology, multiply and develop.
