Neither do maths, physical laws, etc. I think it is wrong and dangerous to equal Human Rights, which are an ethical decision, to religious beliefs, which are cultural construct much closer to "fictional stories" for non-believers. This new trend in anti-humanism carried by Harari, who is read widely, or Peter Singer, is frightening.
Interesting, I interpreted it as human rights not having basis in physical science and therefore all the more important for individuals and society to champion. However I do see how the quote can be seen as equating human rights to cultural fiction of arguable merit, which I agree is dangerous.
