If we didn't figure out the simple stuff like metals and gasoline and oils, but were helped by aliens, who helped the aliens? As likely as it is we might have had some help, with more advanced technology, it seems unlikely that aliens taught us all of this. I mean, if they did, who taught them? Or did they all already know it all? Or did they get privleged and get to figure it out, but we're too stupid too figure anything out? I respect that you think what you do, I just find it far fetched.
Well, they said the grass is greener, so I thought I'd check it out.
