God did not warn him or instruct him on how to build the ark Lucifer AKA Inky did I'm not sure where this idea came from that Lucifer is the Sumerian deity enki but it is such a conjecture Lucifer is a Latin word that means lightbringer and it is used to translate one word that only shows up once in the Hebrew Bible and that's in Isaiah 14 12. the chapter is talking about the downfall of the king of Babylon but it's describing it in a way that seems to parallel a prior Divine Rebellion because of this
Scholars like Michael Heiser have argued it's also talking about when Satan was cast out of heaven and because in the Latin the word for Daystar is Lucifer theologians began associating Satan with that name but there is nothing in Isaiah 14 directly connected with anything surrounding the mythology of enki nor is there anything about enki and Sumerian mythology that sounds like the day stars fall from Isaiah 14. and this is probably why I can't find one biblical scholar or a seriologist that says any biblical author thought Satan was the Sumerian deity enki
