Nothing is a concept utilized by human beings to signify
  absence. Cognitively it is typically represented by a blackness
  with vanishing perspective as visualized internally and
  poetically represented by many metaphors, typically related to
  emotions generally construed as negative but sometimes as
  positive, as in times where the concept of nothing has replaced
  what used to be occupied by God in older times.   How about
  this: Nothing exists because we talk about something referred to
  as nothing.
