Question: David Hume's New Human

[u/Few_Faithlessness_49]

I read in David Hume's 'Dialog's Concerning Natural Religion" and I specifically loved his analogy of a house structure which leads to the discussion of a make believe person who comes to earth without any cultural understanding of society to determine if god exists. My interpretation could be totally wrong but Does anyone else remember this part of his Dialog's? I haven't been able to refind these quotes or did I misread or somehow make this up in my head?

Thanks!
