The claim that the construction of the Suez Canal disproves Earth's curvature reflects a fundamental misunderstanding of both engineering methodology and geodetic science. The Suez Canal, extending approximately 193 kilometers, was built to follow the local horizontal defined by the Earth's gravitational field not a hypothetical straight line through space. Consequently, the canal does not require "adjustments for curvature" in the simplistic sense implied by flat Earth proponents. Rather, its design inherently follows the curvature of the Earth, as do all large-scale engineering projects undertaken using standard geodetic practices.
Surveyors and engineers routinely employ reference ellipsoids, such as WGS84, to account for the Earth’s shape and gravitational anomalies. The concept of “level” on Earth corresponds to the geoid, an equipotential gravitational surface, which by definition curves with the planet. Thus, the canal’s water remains level because it conforms to this curved surface, not because the Earth is flat.
Empirical observations, such as the predictable occlusion of ships on the horizon, the precise functioning of satellite systems, and centuries of astronomical measurement, conclusively support a spherical Earth. To reject these convergent lines of evidence in favour of spurious interpretations betrays a disregard for both scientific rigour and the foundational principles of modern engineering.
