I think you're misunderstanding Google a bit, Aamir. Google doesn't say anything; it merely reports what it finds on web pages. It's up to the user to determine the value of the results.
Yes dear brother, now tell me how many English speaking countries are there in the world? they are five right where English is used as their first language.
1. The United Kingdom
2. The United States of America
3. Canada
4. Australia
5. New Zealand
I agree there are other varieties like South African version and Indian version I don't know about South Africans but English is not used as a first language in India so they are not native speakers their English is similar to Pakistani English.
So to me there are five English speaking countries in the world. And Even in these countries English is different in terms of accents, vocabulary, pronunciations, etc.
Now tell me how many countries are there in the world, I don't know exactly how many but there might be nearly 170 or perhaps more than 200. And most of the countries in the World use English as means of communication, I mean English is a universal language in most of those countries, it is not their first language.
Now, as far as Google is concerned it extracts data out of the web pages that are posted by people from all those 170 or 200 countries, who are not native speakers and who use English as 2nd, 3rd or probably fourth language. So they cannot be as precise as the native speakers are. Do you agree?
And I could trust Google if Google only used web pages by only those five English speaking countries that I mentioned earlier in this post. So that's why I trust more in the native speakers rather than Google.
