The flat Earth theory posits that the Earth is not a sphere, as widely accepted by modern science, but rather a flat, disc-shaped object. Proponents of this theory argue that evidence from everyday observations, such as the appearance of a flat horizon and the lack of visible curvature, supports this view. Photos of Earth from space are widely speculated to be fabricated or manipulated, and that the scientific community has conspired to suppress the truth about the Earth's shape. Flat Earth theorists also posit that gravity is an illusion and that the forces we perceive as gravity are explained by other mechanisms, such as the Earth accelerating upward. A widely recognized theory suggests that the Earth is surrounded by a giant ice wall (Antarctica) that keeps oceans contained, and that space exploration and the heliocentric model of the solar system are hoaxes perpetuated by the scientific community. The belief in a flat Earth was prevalent in many ancient cultures, offering a stark contrast to the widely accepted modern view of the Earth as a spherical planet. While the scientific community asserts the Earth is an oblate spheroid, early civilizations held diverse beliefs regarding the shape of the world. This book explores the ancient flat Earth model, specifically examining how early cultures like the ancient Greeks, Egyptians, and others envisioned the Earth. These beliefs not only influenced their cosmology but also played a role in shaping their understanding of the universe and their place within it.
