My statement wasn't meant to be taken seriously for which I apologise. Although, the same bloodline isnt required when considering the given situation. The giants and humans weren't specifically created. They were, to some extent, always there.
I can't stop laughing. I wonder how anyone would try justifying this crap. I'd argue that this isnt Nakaba's writing and even if it is, the pre-commandment saga wasn't his. Its impossible to fall from that height.
