Answer 1

Back when trees first evolved, there was nothing in the world that could digest wood. For millions of years, when trees died they would fall over and just lay there on the ground, not really rotting or anything. Then huge fires would spread, all over. Then the trees would get buried, and over time the heat and pressure turned them into coal!

That’s where coal comes from!
