That's why people believe Latin Greek or Arabic (western languages) is the oldest language.. So the truth is not the one which most of them speak or believe.. Most of the people believe what their parents tell so they tell their own language as oldest... Muslims want to say Christianity originated from Muslim.. So they believe Adam is Muslim. But who said christian or muslim is the first religion?(may be your parents might told it who don't know the truth)
Just stop talking what you are following is the best one...
Take some time and check things(compare alphabets, words and meaning) and find your self whats the truth..
Most of them speak here don't even know more than 3 or 4 languages, so don't make arguments without knowing things...
So TAMIL is origin of all languages..
The basic reasons are,
1. Tamil words r created by considering the type shape and structure of things. (Crow is kaka in tamil, which make sound ka ka ka.. Cow is madu in Tamil, which sounds maa and many other examples can be given)..
2. Tamil is not originated from any language(People believe it was from Sanskrit, but researches went into failure. Check the records), its a created one...
3. When all language got modified and produced new one for changing world, but Tamil never gone any modification and they really don't need, because they have all things in it...
4. East or west you can see at least a single word from all other languages might be similar to a Tamil word.
5.People want to follow a easy and simple language, but Tamil is not a simple or easy one, so many are modified and created, which lead Tamil to degrade..
6. Their is a solid proof for numbers originated from Tamil, which is then carried out to Sanskrit and then called a arabic numerals..(Just search for numerals in these languages from net and find it out). Many people know zero was invented in India. And most important is still many languages can't find a word having more zeros than zillion or trillion but in Tamil it was named thousands of years ago...
7. Many such things can be written but no space here...
Even after this people will argue about their own kind but I remind them again don't speak what you feel or others tell to you, research and find the truth and go behind it...
Thank you....
