Why do we sleep at night?

[d0wnsized009]

My sleeping cycle is tapped. Or maybe, everyone else sleeping "regularly" at night are really the ones that are tapped. I don't get it though because why do all humans, without question, sleep for a period of time only during the night? I've never questioned monophasic sleep, sleeping for 6-8 hours at night and then staying awake for 16-18 hours
