Before reading your blog, the only thing I knew about Rig Veda was what I read in our textbook about it being the first religious hymns of India.I am overwhelmed and impressed that there were 1,028 hymns and that they were past down for centuries orally before the evolution of text. I think that the importance of these religious hymns is proven in the dedication of memorization by the Hindu people. I do think the Rig Veda is imperative to the time capsule because it shines light on the beginnings of the Hindu religion and Indian culture. It also give us another secular view of why and how religion is vital to humanity and society. 
I liked your final statement and curiosity of how these nomadic people would react to how far we have come in transportation technology. And also agree that we have a lot to learn from the people themselves. However, I didn't gather your opinion of the Rig Veda specifically and why you thought they were important?
