If we were to find a brand new gene previously unseen, one may ask “Where did it come from?”
In the case of Rh negative blood, we are not dealing with something new.
We are dealing with the absence of something very present in most of the human populations:
The D antigen of the Rh blood group system.
This gene deletion took place in at least one of our ancestors. Gene deletions are common, cystic fibrosis for example being the result of several.
It is also possible that blood type O wasn’t first, but rather being a result of the A and/or B antigen being deleted.

I have researched the Alien aspect and the Demigods as well. In the Bible in the Book of Daniel, I believe it talks about the Angels coming down from heaven and making love with the beautiful daughters of man. These Angels would have been fallen Angels and therefore the children that were produced would be Demigods, children of fallen Angels and basically little demons. The Alien aspect is very similar. In ancient times, the God’s had wings and came from the sky. They were called sky Gods. The same theory for the sky Gods they came down and had children with the women of earth. Therefore making those with the Rh negative factor in their blood considered Aliens. This is all from memory. So if you are all that interested in this do some research on the internet and let me know what you come up with ? Anyway those are the 2 reasons I found for the Rh negative factor being in our blood.
