Well I have Minecraft now(YAY!).
When I created my new world in it(Titled ' I HAZ MINECRAFT NOW GUIZ' '-_- ) I spawned ON TOP OF A TREE IN THE JUNGLE XD.
Anyway, I'm currently building my house at night(Please note that I'm on Peaceful & in Creative) & I've been hearing strange noises like someone else is walking around & building!(Please note that I'm also in Singleplayer)
Who or What is it?
Edit:It was just the animals
