Another 2012 idea. Alien seeding?

If one were to put weight into the idea that our human existence has been "aided" by alien life in some way. THat in the past these visitors would help us along every once in a while.

Well could 2012 be the time when the new wave of humans hit earth? You know, the aliens get the new version down here, and it takes a while to get it into cycle and mabye 2012, for lack of a better word is the inflection point were the new version is dominat vs the old one.

Could these supposed hybrid, star child, Indigo child be the ushering in of a new human? Thoughts, ideas, did someone already think this?
