Oldest language could be a distinct language that has preserved its uniqueness. Due to the ice age, European languages can not be the oldest.
The isolation of these tribes and the long human habitation in these regions could make the languages some of the oldest as well as primitive.
I don't think they have actually been isolated for 60,000 years though. If I understand correctly, they chose to isolate in the 1800's because the British were kidnapping people. Before that they had contact with other Andaman islanders at least. For example, apparently the Sentinelese may speak a language of the Ongan family[1], which would mean that their language most likely diverged sometime within the last millennium or two, I think.
Personally, I think most languages are old, except for constructed languages like Toki Pona that have only existed for a short time.
How do you measure the language change [2]? There are several approaches, the one I remember reading about is, you fetch the most basic kernel of a language, like very simple key words (like relations, food, feelings and so on) for about 100 words and then see how many of those words have changed since say last 10 years, last 50 years and 100 years and so on. You try going back as long as you can and you loose few words from 100 words you started, that's you delta.

The "after some practice" makes this a bit of a squishy claim. For example, Malayalam and Tamil split less than 1000 years ago and are both descendants of Old Tamil. I would be surprised if "after some practice" a Malayalam speaker couldn't also read Old Tamil, or for that matter Modern Tamil (and vice versa for a Modern Tamil speaker learning Malayalam).
So is Tamil somehow older than Malayalam? I think not.
For instance, we have very solid evidence (but still circumstantial, and therefore this is technically an hypothesis) that the Greek letter η, that now stands for /i/, had a long eh-like sound, likely /ε:/, for this and due to many other changes, we can say that were a Modern Greek speaker to speak with a Greek from the 5th century BC, they would have understood barely anything, barring certain specific words. From tracing how the language changed, according to the extent evidence, we can probably say that this speaker, however, would have mostly (but with difficulty) understood a speaker from 12th century Constantinople in simple day-to-day conversations. At the very least, the two speakers would have the same sound inventories and similar grammar, but somewhat different vocabularies.
I still agree with you that saying one language is older than another is meaningless. At most we can say that a language is probably more conservative than others.
Here is poem that speaks about children being joyous, and how they playfully eat food. A simple ordeal in everyday life. Its about 7 lines and everyday speaker still understands all of it.

Written Tamil have continuously evolved all along, the recent being around 1950 when printing became prevalent. The language itself changed very little, however only written letters survive and to know what was written 1000 years before you need some training.
Expert opinions might be different. Hope I am getting some information.

Tamil has two forms. Sentamil and Koduntamil, both survived till date. Sentamil is the formal/literary form and Koduntamil is the colloquial form used by common people. Koduntamil is made of simplified and shortened forms of words from Sentamil, some loan words and slang words. Due to the cultural and political influences in the last few centuries, there are many loan words from European and Persian languages in Koduntamil.
Other Dravidian languages[4] such as Telugu, Malayalam and Kannada has heavy influence of Sanskrit. There were efforts to Sankritise Tamil as well by using Sankrit words in Tamil syntax, which was called Manipravalam. Manipravalam was in use till early 20th century. In the beginning of 20th century, Tanittamil Iyakkam[5] aka Pure Tamil Movement restored the language and Maripravalam is no more in use. The formal Tamil used today, such as in news bulletins and official documents, is very close to the classical form.
Pure Tamil Movement, the two language policy[6] adopted by Tamil Nadu government and related efforts helped preserve the language. Although the Tamil speaking population is lesser compared to other languages such as Hindi and Telugu, Tamil has a thriving art, literature and media industry which are economically successful too.
Recent archeological research at Keezhadi has revealed a 6th century BCE Sangam era settlement in Vaigai river valley[7]. If more research confirms the findings, Tamil would be one among the oldest surviving classical languages.

It is lacking in modern technical literature and comics. Most kids in school memorize tirukural, without understanding a word. Pushing the burden on preserving old language on kids is actually driving them from the language itself.
Can you elaborate on how you concluded that Tamil has become less usable? Citing sources will be helpful.
Such a weird notion. It seems to me that 'old' for a language is often used to imply that it is 'important' (culturally? presumably yes.), which feels, well, not racist, but maybe 'linguist' -- OK, that word is already occupied... Even fighting exists about which language is 'oldest' -- could you please make up the rules of the game before playing?
Anyway -- this is just me not understanding what people mean.
