In the Vedas it says "that which is closest to the truth lasts longest," which certainly would include astrology, developed around 7,000 years ago.
Not that it matters much, but I'd like to see your evidence of this 7000 year old date.
For instance, wikipedia tells me of the history of astrology in India:
The earliest use of the term jyotiṣa is in the sense of a Vedanga, an auxiliary discipline of Vedic religion. The only work of this class to have survived is the Vedanga Jyotisha, which contains rules for tracking the motions of the sun and the moon in the context of a five-year intercalation cycle. The date of this work is uncertain, as its late style of language and composition, consistent with the last centuries BC, albeit pre-Mauryan, conflicts with some internal evidence of a much earlier date in the 2nd millennium BC.[68][69]
It also has this to say:
Babylonian astrology was the first organized system of astrology, arising in the 2nd millennium BC.[13] There is speculation that astrology of some form appeared in the Sumerian period in the 3rd millennium BC, but the isolated references to ancient celestial omens dated to this period are not considered sufficient evidence to demonstrate an integrated theory of astrology.[14] The history of scholarly celestial divination is therefore generally reported to begin with late Old Babylonian texts (c. 1800 BC), continuing through the Middle Babylonian and Middle Assyrian periods (c. 1200 BC).[15]
So between four and five thousand years old, maybe a thousand years older than that if the Sumerian claims are correct.
