Ye Grande Olde Prometheus Excel Jockey timeline curve

Bored out of my wits i put in the dates of the archaeological 'invitations' the site uploaded into excel (the discovery dates the site mentioned). There were 2 findings for one year, around 1760BC (memorys poor, i did this a few days ago). So i only used one of those. Anyway, it makes a pretty decent curve, and kind of shows that if someone was meddling with us, they stopped at a certain point in history. That point in history would have been around 500BC to 1BC, guesstimating. So, you could infer from this that they were happy with the progress of their little pinky brown people project. But what would have made them so happy? Whilst there was signs of civilisation and society then, it was pretty barbaric. One step out of line could cost you your foot, leg, well, there were some pretty spectacular hoorrific punishments meeted out then. But maybe they thought we'd stay like that for some time, and we've advanced a lot quicker than they were able to predict. i say this because it sems a feature of their technology, rapid genetic advancement. But maybe the drawback is unforseen consequences. Any blue muppet can speculate what will happen in an experiment, but until youve done an experiment you don't know. Maybe their experiments were their downfall, and we meet them as theyre circling the drain (entropy-wise)
