I like the dark movie theater analogy for beginners e.g. in a dark theater, how would you know what row you're sitting in? You'd ask the row in front of you "what row are you in?" and they'd shake their head and ask the row in front of them and so on until they finally get to the first row, who would know they're in the first row, and at which point they can answer the second row's question all the way back to the row that originally asked the question.
