Hello. The way that works, you have to infer the existence of A for the existence of B and the existence of B for the existence of A.

Direct copies only work as an argument if the item is an Original, as in the idea of a thing wholly onto itself without an external influence of any sort.

you might argue that it's derived as in Originated from, borrowed from, a sourced to, an antecedent of, an allusion towards. I could continue. sort of like how Star Wars Episode II and Star Wars Episode I are derived from Star Wars Episode IV. :)
