Thanks midcan. I'm not being difficult, I just like to try and agree on terms.
"Everything follows from your living." It does doesn't it? I mean this is a bit like the old tree falling in the forest conundrum.
Being alive is a prerequisite for consciousness.
Having a brain with a human cerebral cortex is also a prerequiste for consciousness and self-awareness.
But consciousness and self-awareness are entirely subjective. Get more than one fully functioning (cognitive) human in one place and they'll start to work out shared understandings.
With their senses they will recognise various things around them but unless they have a shared language and culture then they'll not be able to communicate what their senses perceive.
So, they develop agreed understandings. "We'll call that a chair". "Chairs can be used to sit in". "That chair belongs to me because I made it."
Human rights are an agreement as well. They don't come from a deity, they come from humans agreeing on things like not killing each other, thus producing the understanding of the right to live.
Human rights can change by agreement. It used to be that it was a human right for one human to own another. In many countries in the world that right has now been displaced by the understanding that every human being has the right not to be enslaved. That human right, not to be enslaved, has great currency in the world, even though in many places it's ignored. Being ignored doesn't kill its validity. In fact the idea has such currency that is of a form of right we call, by agreement, a universal human right:
