It is saying, for 3000 years [9000 less 6000], all of humanity was in dormency mode, did not graduate to recall a single name or evidence directly affirming speech.
LOL
Nonsense. It is saying that for over 11,000 years we have evidence that affirms human speech. Over 11,000 years. It does not mean that speech did not develop even further in the past, hundreds of thousands of years, maybe even millions of years in the past, but we know that for at least 11,000 years humans have also been recording written symbols and speech predated even that.
Maybe because this notion simply does not exist!
Obviously the notion exists. We have examples of speech for many marine mammals, birds, our cousins the other primates, elephants, the great cats, hyenas, hippos, in fact just about everywhere you look.
Now granted you are free to keep spouting the stuff you believe, but over here on the science side we need some evidence.
Until information has been shown to suggest that "human speech" is in anyway different in nature than speech by any other species, all we have is another fairy tale.
