Why? And You can't duplicate skills so if you have one 8 year old you can't have the other. I would pick the 8 year old girl over the boy if anything because the men can continue to reproduce a lot longer than women can, there fore the 8 year old girl when mature can help repopulate more than the boy child can.
Also Remember This could be the satrt of a whole new world we are talking about, so emotion should play no part in it. It should be the best for the human race not just for your feelings.
