many languages have gone extinct and continue to go extinct every year. It IS possible for a language to be removed (native Indian languages in America, replaced by English , South America lost many languages to Spanish - it is possible to lose a language through overpowering of other language, its more difficult to replace cultural affiliations - hence South American christian community has many local traditions embedded into their christian celebrations)
You cannot use the modern analogy of wiping out of Native Americans to something like IVC.
IVC were a very advanced and sophisticated civilization unlike the tribal society of the native Americans. Its impossible to wipe out such a old, powerful and huge civilization. It was the most advanced civilization of its time.
stellar constellations are definite, however the knowledge passing through generations means there may be changes in the text
This is impossible in sanskrit.
three issues here:
1) I am not in the business of calling something perfect or imperfect. it is man made and it could be a genius invention but its never infallible
2) even if we assume its infallible, you clearly stated the condition "know the correct usage" - there could be changes in the usage
3) my opinions is more towards this third point: there could be a change in the content of the text willingly (improvements/adding other myths/ amalgamations with other groups of peoples - quite common in intermingling process of groups of people).
You assume this because you do not understand the sophistication of Sanskrit.
Sanskrit has some 4000 rules in total. These rules are so scientific and logical in nature that its based purely on mathematical and algebraic algorithms. It so sophisticated, that if you use these rules, you can create rules for ANY language on earth. (That is why Tamil has sanskrit grammar rules)
Sanskrit rules consist of Data about data itself. (What we call meta data today). The combination of these rules form a complete database which are divided into 4 parts.
First is the Aksharasam Amanaya: This contains data to pronounciate any word. Consisting of 14 shiv sutras that in combination forms words. These are split into Anubandha (which form end of words) and pratyahara which gives all letters before the anubandha. Among the hundreds of combination possible in pratyahar, only 42 is used in sanskrit.
Second is the Sutrapatha: which has 4000 sutras
Third is Datupatha : This has 1967 verb roots along with 2014 kandvadi roots
Final is Ghanpatha: This has pertinent items like primitive nominal bases and avayayas (words that do not change)
The rules inside these four data base is the Meta data for sanskrit. This does not exist in any other language in the world.
Sanskrit also have recursive function ( like function calling a method in computer programming), so in these 4000 sutras which form words make use of sutras which were used earlier.
sanskrit also has Loph, which is like a null value. So words are joined using this Loph i.e break, but yet form a single pada.
Similarly Sanskrit uses modern concepts of computer programming like polymorphism, Inheritence and sets, If then else conditions, as part of its rules.
This ensures that the language is never corrupted.
Also there are multiple schools which taught Vedas , all independent of each other and yet all of them follow the same vedas without any change or mistake. These schools later formed the gotras known as Gritsamada, Vishvamitra, Vamadeva, Atri, Angiras, Bharadvaja, Vasishta and Agastya.
The Vedas had their own index and each of them had a fixed number of verses. They are classified as Mandalas, Ashtakas, Adhyayas, Vargas, and Suktas.
In addition these were cross referenced with the Upanishads, Shakha, Brahmana, Aranyaka, Sutra Grantha, Smriti, Shashtra, Itihaas and Neeti.
Any mistake would be caught out and any edition would be caught out too, since it will put the entire index out of alignment.
For each type of sentences, rather than limited number of words and a number of grammar rules to follow, Sanskrit has different independent words
This is why even tough sanskrit spread all over India, from south to North, it never ever changed. Not once.
That is why its a perfect language. Its difficult to explain this in a single post. But I hope you have understood the level of sophistication in sanskrit that prevents errors and correct errors.
If you consider Sanskrit like any other language like eglish, then one will make such mistaken assumptions. But if one is aware of how sophisticated sanskrit really is, one will know with a certainty that its not possible for it to go wrong ever.
