The word ‘blood’ was added in Acts 17:26. And there are two different days of flesh beings created/formed in Genesis 1 and 2.
Are you saying that the human race has been sort of infiltrated by some other mammal? I.e. we all have some sort of neandrethal blood in us?
If so I’d like to bring up the fact that separate species can’t reproduce successfully. Also, the sex with an animal is a crime of great proportions in scripture. Also, that mankind is the only creature made in God’s image.
