This is all so inaccurate and/or totally mistaken that I don't know
where to begin. I'll try to take it point-by-point, and I'll try to
concentrate only on major errors of fact and shaky assumptions rather
than on what can be considered allowable hyperbole for a general
audience. And I'll leave discussion of ancient Greek and Near Eastern
zero concepts for those more knowledgeable about them. It may spread out
over two postings...

See R. C. Gupta, "Who Invented the Zero?", _Ganita Bharati_ 17,
1--4 (1995), 45--61, for a much more knowledgeable and informative
overview of the subject. This author's chief mistake seems to be
assuming that the three best-known Indian mathematicians---Aryabhata,
Brahmagupta, and Bhaskara II---are necessarily the inventors of
various developments. The Sanskrit word "sunya" (void, sky) for
a zero-marker is found in Pingala's Chandahsutra, probably no later
than 200 B.C. Certainly, Indian mathematicians were habitually using
a symbol and operations for zero long before Aryabhata in the 6th c. C.E.
