I didn't realize that bones only have to be declared human but must be proven otherwise. How much more objective can you get than that?!
I am not responsible for what you don't know. Anthropologists and other forensic specialists determine what types of bones they are. They have determined that we have bones (sic) and of what type they are. This has been done.
Objectivity is dealing fairly with the data. Your choice to ignore the data is driven by the fact that you cannot deal with it. Yours is not objective. It is denialism.
