According to John Major Jenkins, a leading independent researcher of ancient cosmology:
“Our understanding of the true age of the ancient Vedic civilization has undergone a well-documented revolution. Feuerstein, Frawley, and Kak have shown conclusively (In Search of the Cradle of Civilization) that the long-accepted age of the Vedic culture—erroneously dated by scholars parading a series of assumptions and unscientific arguments to roughly 1500 BC is much too recent. Evidence comes from geological, archaeological, and literary sources as well as the astronomical references within Vedic literature.
The corrected dating to eras far prior to 1500 BC was made possible by recognizing that precessional eras are encoded in Vedic mythology, and were recorded by ancient Vedic astronomers. As a result, the Indus Valley civilization appears to be a possible cradle of civilization, dated conservatively to 7000 BC.
Western India may thus be a true source of the civilizing impulse that fed Anatolia in Turkey, with its complex Goddess-worshipping city-states of Çatal Hüyük and Hacilar. However, there are layers upon layers of even older astronomical references, and legends persist that the true “cradle” might be found further to the north, in Tibet or nearby Central Asia.
The work of these three writers shows that biases and assumptions within scholarly discourse can prevent an accurate modeling of history and an underestimation of the accomplishments of ancient cultures. The analogous situation in modern Egyptology and Mesoamerican studies also requires that well-documented new theories — often exhaustively argued, interdisciplinary, and oriented toward a progressive synthesis of new data — should be appraised fairly and without bias.
Next to the Australian aborigines, the Vedic civilization is perhaps the oldest continuous living tradition in the world. Its extremely ancient doctrines and insights into human spirituality are unsurpassed. We might expect that its cosmology and science of time has been as misunderstood as its true antiquity. In looking closely at Vedic doctrines of time, spiritual growth, calendars, and astronomy, we will see that a central core idea is that of our periodic alignment to the Galactic Center. And, according to these ancient Vedic beliefs, the galactic alignment we are currently experiencing heralds our shift from a millennia-long descent of deepening spiritual darkness to a new era of light and ascending consciousness. ”
(What is brought out in this article (taken from the Internet) is that astronomical references can be verified when one has an open mind. Yet, European colonialism apparently produced writers claiming that the ‘back peoples’ of Egypt, Mesopotamia and India could not have taught ‘white’ Europeans anything. Presumably, ‘Greeks’ provided all the learning and Judaism provided the necessary religious perspective to Europe long before anyone else became civilised!)
