The History of the Vymanika Shastra, page 5

To add more to your problems...now they found a ancient city near Jodhpur (Rajasthan) India where the bodies were found like mohanjodaro, highly radio-active. (few thousand years old)

Significance: Couple miles from Jodhpur is Mandore garden...which is said to be "Mandodari's parents home" ...Mandodari was Ravan's wife...(from Ramayana)...
So the war in ramayana was also atomic war??? as if Ravan is fighting with Ram then Ravan's wife's family (who ruled near Mandore probably some ancient city before jodhpur was established in 14 th centuary....in Ramayana time) must have helped Ravana...and that way they were enemy of Rama too...

So the result of being Ram's enemy is what we have found now in the form of this ancient city (buried, they are still excavating it, it was found in late 2006)
answer to the language mystery can be solved only by one understanding that India wasn't just the India we see now...it was lot bigger in size...I can't guess from where to where...
About finding more proofs...
one needs to learn the Indian way of development of science...science in India which is mentioned in these scriptures. The science as I believe wasn't the way we have in our times...it was closely tied with religion/spirituality. This is why its so hard to prove everything...
like the so called engery to levitate ..."lagima" if I remember the name right...
We know yoga is great and works wonderfully...but we reject the part which we don't understand now...it's what I have seen at many other places...
I got into this ancient Indian stuff research for my calc 2 math project...
and what I found...
that the arabic numbers...are actully indian number system...and europeans called it arabic because arab scholars got it from indian and then in probably in 13 th centuary it went to europe...
tons of other stuffs like that...if we legitimately change all the names and give proper credits...half the calculus books will be credited to indian names...(no exaggeration here) ...literally half atleast...
About the colonists...yes...they were ruling the world and they could do whatever they want...and they have changed the history the way they wanted...this is why its so hard to convince someone born in west (or a white person)...
funny thing...I was discussing about this guys work and concept about zero and infinity with my instructor in the class...and this white guy after a while (as he didn't understand the concept at all) told me that I probably don't understand concept of zero as English is my second language...(I haven't scored less than 97%-98% in last 10 math classess I took in last 3 semesters, and few of them are DiffEq., linear algebra, trig. etc.)
And I laughed about it, what else can I do. He scores in that same class a B or a C (in his first language) and I am close to perfect score even if its my second language...and he talks to me like I am learning concept of zero and infinity in second language...(which actually came from India, no need for me to prove that too....gazillion online sources, books will say that...
I will say, come out of "colonial mentality" and things will be different...it doesn't make India a great place now if they had some really advanced civilization in the past...
only thing which interests me, if its true and they disappeared like the way we can't even find enough proofs for the things those scriptures say, then we are on the verge of the same thing....we have the technology to destroy ourselves again...so intelligent thing is not to fight for if it was true or not...intelligent thing is to conclude that if it was true and they lost so much due to this atomic war, which is called "Mahabharata", then we better be carefull that we don't let that happen again in our time again....or after a few thousands year later some civilization might find scriptures dated few thousand years back and cities full of dead by some atomic bombs...
