What are the "natural rights" of man, where did they come from, and how are they "self-evident"?

The "natural rights" of a man is the rights you're born with. They came from you being born or the constitution. And they are "self-evident" because you don't have to explain what you're doing like when you're getting a house you don't really have to explain why you want that house. (All they might care about is the money you're paying them lol)

Explanation:

Natural Rights- Things like getting property or a house or something like that.

Hope this helped!
