So to summarize, Finally, if Vedas are the words of God, then how can Rishis be called the authors of Vedic hymns ? We know that these are the universal laws of physics which dictate the functioning of our Universe.
If God exists, then God must have created these laws.
On the contrary, the Vedas speak of the mighty Sarasvati River and other places indigenous to India. Max Muller, the principal architect of the Aryan Invasion theory, admitted the purely speculative nature of his Vedic chronology, and in his last work published shortly before his death, The Six Systems of Indian Philosophy, he wrote: "Whatever may be the date of the Vedic hymns, whether 15 hundred or 15,000 B. E., they have their own unique place and stand by themselves in the literature of the world."For example, the language and symbolism found on the Harappan seals are very Vedic.
To date, no evidence for a foreign intrusion has been found, neither archaeological, linguistic, cultural nor genetic. We find the Om symbol, the leaf of the Asvatta or holy banyan tree, as well as the swastika, or sign of auspiciousness, mentioned throughout the Vedas.
Now finally when the rains returned after the terrible 14 year old drought, Vyasa – the son of a fisher-woman sat down to collect all the existing vedic hymns and finally compiled these scattered hymns into four different collections – the Rigveda, Samaveda, Yajurveda and Atharvaveda.
