ridiculous. "humanity" recognizes that killing of others is generally wrong because they value their life as well. even animals do to some extent and they can't write. if anything, this understanding is why it was written into the bible as with any understanding. it first starts out as a thought, forms into a concept, passed orally and then written down by some. but of course, not every concept or idea is legitimate or even worthy. this is why both humans and animals usually do not predate on their own tribe members since they are dependent on them and vice versa or furthering their dna or species. that is also why the bible has many verses that condone the killing of others who are unlike another. as far as understanding the golden rule, that is an acknowledgement or greater awareness or understanding that all life values itself and is trying to survive and so therefore greater compassion. also, humans and some animals alike are capable of compassion or affection more or less. the bible is not the true 'origin' of wisdom. it is just written down by someone just like there is erroneous stuff as well. also, understanding can occur independent of any written text by one's own experience. this is just so obvious to be missed. of course not. again ignorantly taking credit again. it's that people eventually fought for their rights and the parts of the bible condoning such inequality was not used to justify it by law. it was for social and political reasons rather than religious because religion and most philosophies did not represent their rights.
