Minecraft wiki entry for Superflat_survival, associated text: Nightime is the way you will acquire the majority of your resources. However, during the first night, you need to fight against monsters without any weapons. You will likely die a lot on the first few nights. Making an emergency shelter (digging straight down 3 blocks, and placing dirt or wool above your head, then waiting till the morning) or craft a bed and sleep is a bad idea, as most resources are obtainable from monsters.
