Besides being interesting in itself, this video also relates to the history of Buddhism. American Buddhists who are not from a traditionally Buddhist region may find it interesting that the ancient origins of most Europeans are Aryan, or Indo-European or Indo-Iranian. To me this is not a big deal emotionally and most of us came to learn Buddhism long before we knew of an ancient relationship like this. Nonetheless, it is valuable to recognize roots that reach deep into the past over a wide geographic area. ABN
Among Indo-European languages, Lithuanian is conservative in some aspects of its grammar and phonology, retaining archaic features otherwise found only in ancient languages such as Sanskrit[7] (particularly its early form, Vedic Sanskrit) or Ancient Greek. For this reason, it is an important source for the reconstruction of Proto-Indo-European despite its late attestation (with the earliest texts dating only to c. 1500).[4]

Anyone wishing to hear how Indo-Europeans spoke should come and listen to a Lithuanian peasant.

Aryan’s came OUT OF India! It’s the white, Eurocentric sense of superiority that created the MYTH of the Aryan invasion (no evidence of this) or Aryan migration (no evidence of this) or Aryan picnic (no evidence of this either ;-). It first began with the ridiculous notion that earth is only 5 or 6 thousand years old (according to Biblical “scholars”, so they had to fit the history of India into that time frame.)
Hindu culture is at least 70,000 to 90,000 years old. There is archaeological evidence of Hindu culture that dates back 10,000 years. Genomic evidence indicates that the largest gene pool in Asia is centered in India and that gene pool spread out of India over millennial.
Aryans were originally from India and came out of Hindu culture, not the other way around.
