Whilst some players will set defeating these monsters as an objective, Minecraft is a sandbox game and has no 'end' - you're free to forever explore and create in the (literally) infinite world.
Since the game launched, two bosses have been added - the Ender Dragon and the Wither - these will take a lot of skill and resources to defeat. but at night, you're likely to find yourself fending off fearsome creatures including zombies and the infamous creeper. During the daytime, Minecraftia is your oyster: you can explore, mine, build, and craft until your heart is content. The world of Minecraft is filled with 'blocks' which make up all of your surroundings - these can be broken, placed, and used to craft items. Minecraft is an open-world sandbox game that launched in 2011.
