Is there something about RH Negative blood type?

[luis]

I saw this video https://www.youtube.com/watch?v=N1RZ8FZrNiA which is pretty interesting, it say RH Negative blood type is pretty rare, scientist do not know how it could even exist here on earth and it may be "alien". What do you think about it? We know the Gods did have kids here on earth, is it possible this blood type originated from them?
