It's a human idea and a human invention, developed in a certain historical context. Calling it "made up" is pejorative, for sure, but not at all wrong.

It isn't like the Hubble Deep Field has a pattern that spells out "all human beings are born free and equal" or something.

I agree with GP that human rights are made up but would love to hear why and how you think they aren't. That would be a far better read than this pointless post that doesn't contribute anything to discussion.

If you asked me what human rights I have I couldn't tell you. Do I pick stuff from the bill of rights, do I pick stuff from my religion? How do I know what rights I have?
