Human Rights do exist, and are protected at a International level: https://en.m.wikipedia.org/wiki/International_human_rights_law
The EU explicitly references these in their documentation: https://commission.europa.eu/document/download/7a3e9980-5fda-4760-8f25-bc5571806033_en?filename=240719_CSDD_FAQ_final.pdf
Qatar even has a committee specifically created to oversee Human rights, although it's effectiveness is debatable: https://en.m.wikipedia.org/wiki/National_Human_Rights_Committee_(Qatar)
I mean the links I provided detail what Human rights are. Just because some places choose not to implement them doesn't mean they don't exist.
Also Human Rights can be traced back much further than Christianity, arguably 725 BC or older: https://en.m.wikipedia.org/wiki/History_of_human_rights
