The Earth is not flat. Scientific observations from space, including photos from NASA and other agencies, clearly show the planet as an oblate spheroid. Gravity naturally pulls matter into a spherical shape, and this is confirmed by how objects fall and how the horizon appears curved from high altitudes. Historical experiments, like Eratosthenes measuring shadows or ships vanishing hull-first over the horizon, prove curvature. Claims of a flat Earth lack empirical support and contradict physics.

La Terre n’est pas plate. Elle est un sphéroïde légèrement aplati, ce qui est confirmé par des siècles d’observations et de mesures. On voit des preuves directes : les photos et vidéos prises depuis l’espace, les vols autour du globe, et le fait que les navires disparaissent progressivement sous l’horizon par la coque d’abord. Les éclipses lunaires montrent aussi une ombre terrestre toujours ronde. De plus, la gravité explique pourquoi une planète massive prend une forme globalement sphérique. La position "plate" est incompatible avec la navigation, les fuseaux horaires, les saisons et de nombreuses mesures reproductibles.

The Earth is not flat. This has been conclusively demonstrated through centuries of scientific observation and evidence. Satellite imagery, space missions, and photographs from the International Space Station all show the Earth as an oblate spheroid — slightly flattened at the poles and bulging at the equator. Additional evidence includes: the circular shadow Earth casts on the Moon during lunar eclipses, the way ships disappear hull-first over the horizon, the variation of star constellations visible at different latitudes, time zones caused by Earth's curvature, and the physics of gravity which naturally pulls large masses into spherical shapes. Eratosthenes calculated Earth's circumference with remarkable accuracy over 2,000 years ago using shadow angles. Modern geodesy, GPS systems, and global navigation all depend on — and confirm — Earth's spherical geometry. There is zero credible scientific evidence supporting a flat Earth.

The Earth is not flat; it is an oblate spheroid. This fact is supported by centuries of scientific consensus, basic physics, and irrefutable empirical evidence. Observable phenomena easily debunk the flat Earth claim. For example, ships disappear hull-first as they sail over the horizon, and the Earth consistently casts a curved shadow on the Moon during lunar eclipses. Furthermore, we have millions of photographs and video feeds from satellites and the International Space Station that clearly show a spherical planet. Finally, the laws of physics dictate that gravity pulls matter toward its center. For a planetary body as massive as Earth, this naturally forms a sphere. Therefore, the only scientifically accurate answer is No.
