What do the pictograms tell us?

Sometimes, truth is simple, and you find it between the lines. So what do the pictograms tell us? Archaeological digs, earth civilizations with no contact one another, which implies that these civilizations were not only continents apart, but also chronologically distant. And yet....they all have the same planetary system depicted on their wall paintings...so it was all very ancient pictograms...wherever they were found must had been primitive. So what does this tell us? That Earth had been visited quite often by the sjs or the blue guys, whatever, in the old time, and they were worshiped like gods. The pictogram shows men worshiping the tall guy who points to the star system. So were them there to tell us, hey we made you, worship us, as you should? I believe that's, what Shaw had in mind for starting this mission. Let's go find our parents...our creators...our Gods.... And then the trap. We were so wrong and the like... So what if the sjs had simply discovered our planet in the ancient times, and did exactly what they always had, whenever they found a new planet with life (or only our planet): Take by force a few of us with them, for sacrifice, for impregnation and birth giving to news sjs, or just using us as live stock for their experiments for creating the xenos or whatsoever... The fear they stroke to our ancestors forced them to worship the sjs like Gods..or our poor ancestors would never find out what happened to those taken by the sjs... And even further, after the evolution had made us capable for space travel and maybe sending a Prometheus class vessel to the star system, it would trigger their counter measures to wipe out Earth as a possible threat of their race. The fact that we find no sjs, apparently alive on LV, might also have something to do, with the kidnapping of our ancestors in the past. Maybe showing a slowly dying race, struggling to find a way to immortality, and needed hopelessly our live stock to implement it. Share your thoughts. It's free and most welcome.
