Just look at the stuff! Its obviously related! Plus we have an origin legend that the arts came from India. What more proof do you need?
well, I wouldn't rely on a legend as proof. Creation myths and legends do serve a purpose. they can give a group of people an identity and a purpose, and so contain a level of truth, but that doesn't necessarily mean it is historically accurate. This holds true for both religious based creation myths like the Book of Genesis in the Bible, and also for the many creation myths that we have in the martial arts.
Do I believe that Tibetan White Crane was created when a meditating lama witnessed a battle between a crane and a mountain ape in the hills of Tibet? No, not really, but the story acts to give an identity to the system and gives a sense of what kind of movement the art incorporates.
Many times a martial system was created by someone of lowly social status. The art may be very effective and widely practiced, but nobody wants to admit that it was created by a street sweeper in China in 1641. So instead, stories are created that connect the creation of the art to an important historical military figure, or a mysterious wandering monk (bagua here). I think General Kwan has the creation of dozens of style attributed to him. Do I believe he did it? No way.
Now as for kalarippayattu and Damo, let's assume for a moment that Damo was a historical figure, and he did introduce physical excercises to the Shaolin Monks, that became the beginnings of Shaolin martial arts. Damo is placed some 1500 years ago. Did kalarippayattu even exist back then? I am sure fighting systems did exist in India back then, but I doubt if kalarippayattu in any recognizable form, or by that name, did. Martial arts change from generation to generation. Probably a precursor to Kalarippayattu did exist back then, and it gradually became what we know of as kalarippayattu today. But, I don't think it is possible to link two martial arts that exist today, with something that may have happened 1500 years ago. If Damo did exist, and if he did introduce the beginnings of martial arts to Shaolin, it probably was derived from an Indian martial art. However, it was probably not kalarippayattu as we know it today.
