I am lost

One day, when I woke up, I was on an island — sorry, a jungle island. I wanted to escape here. So I started by making a small shelter just with a few leaves under a big tree. After that, with a rock and a long stick, I would make a spear. And with that, I would look for a water source and animals to hunt. As it gets dark, I would look for small sticks and a flint. I would finish day one like that. On the second day, I would do a raft hunt for food, get water, send smoke signals, and write S.O.S. in the dirt, and if I had time, I would try to build a bigger shelter with wood planks. On the third day, I would stock up on food and fresh water and finish my raft, finally ending my time on the island. With the raft, I would dry fish and eat them, and with the coconuts, I would drink their water, or I would save rainwater to drink until I find land. At the end, I survived and lived happily.
