I am not sure why it is thought-provoking for a website to lie to you? There is plenty of real history and demography to read about.
For example my draw died as a newborn (allegedly 50% died before 5), which made me think how many humans never really got to experience life.
Was the story or stats true? I dunno. But it makes sense, and I poked around some of the sources and it was just fun to play with.
