There Is no curvature and the motion of the Earth has never been proven once. The current model Is clearly a lie and If you look In to It properly you will come to that conclusion. I started to look In to this four months ago after two months I realized the Heliocentric model Is a Jesuit lie.
I'm not attached to Flat Earth but the current model Is only accepted through brainwashing It Is not backed by the scientific method.
