I do not deny that many of the kids these days are far ahead in some ways than their predesessors, which also has something to do with the frequence of the overall awareness of Earth. The thing I say is that they do not have to be from other star systems to be so. Most of those children I have met that was kind of magical was either humans or of the elemental kingdom of Earth (the children of Gaea). I have no idea about numbers either though when I observe (and listen to my inner self) I see far more humans than I see anyone else and it is a rarity to see those from the stars where I live. There are probably places where they are more plentyful, that I do not know. But I know that even if those beings that come here for the first time from the stars is only 1-2% then that is still many in a specie that consist of several billion. What would the point be in filling the classroom with teachers and no students?
