Astrology originated in ancient Egypt around 4200 BC and was used by many ancient civilizations to foretell events and health based on the positioning of planets. The Chaldeans were the first to create astrological charts mapping the 12 constellations and dividing the sky into 12 houses to represent areas of life influenced by planetary positioning. While astrology was historically considered a science, the modern scientific community rejects astrology as it has found no evidence that planetary positions can actually affect people or events on Earth in a way that is consistent with biology and physics.
