dna collecting
just like a facebook app
it only takes one of your relatives to sign up and give dna..
then you and the rest of your family have been mapped
they are stocking a DNA ark
the dna will be safely saved in (space)?
then after the destruction of mankind by flood, fire, asteroid.. (pick your fav doomsday)
they will selectively clone a superior human race to carry on
so it is kind of like the rapture that was prophesied
except its not our physical bodies or souls being taken to heaven (space)
it is our DNA
