Oh someone did... Huh. Must've got mixed up.
I haven't heard they go back to Cain. I thought it stopped at Noah. There's some legend about Noah's corpse and something they forgot and waiting for the corpse to tell them what they forgot. I forgot how it goes! Ironic. Probably conflating two things, too.
I think the point about calling God the "architect of the universe" is that anyone from any religion can agree that the universe is perfectly designed. But, we're more of a work in progress, like little architects building little temples, in a fairly obvious allusion to Jesus' statement that he'll rebuild this temple in three days - that being himself.
