Wrong. It is you who keeps shifting the goalposts.
The quoted statements are clear, and clearly wrong. They may have been the wisdom of the day when they were made, but it doesn't make them correct in light of modern knowledge, e.g. human origins, oldest fossil, etc.
As regards the number zero, it was known and used around the world before Indian contribution. The Indian contribution was important, but it is arrogant and disrespectful to suggest that it was the most important factor in the evolution of mathematics.
Bottom line, I am not denying the contribution of people from this region; what I am disputing is the "Out of India" types of claims which denigrate other cultures around the world and claim that everything originated here and radiated out.
