I suspect that my (entirely unserious) post has led to Naomi leaving the thread alone permanently*, so I suspect that you won't get an answer to your most recent questions, Atheist.
I think that Naomi has in the past posted more extensively about this. I might try to find some of those later, although most can presumably be found also from googling such phrases as "ancient astronauts" and "helicopter heiroglyphs", among others. It's worth stressing that the evidence for ancient alien visits is somewhat dubious, and on at least one occasion even fabricated (not by Naomi, I hasten to add, but certainly by her sources); and also seems to me to rely on doing ancient societies too little credit (ie, not taking their imagination or technological skills into account).
