My life as a alien changing kid

My life changed when a meteorite came down from the sky and landed in the forest. But the meteorite was not a meteorite at all but it was a capsule containing something. "A watch but what would a watch be doing in outer space?" I said to myself. Then I reached out for it and then it went into a liquid based state after it got on my arm it returned to physical state. I fiddled with the watch and the dial popped up and a silhouette appeared on the dial. "Cool" I said to myself. I push the button then I turned into some sort of alien that its head on fire. Unfortunately, I set a tree on fire when I touched it though but it was put out by putting dirt on it.
