A piece of evidence that confirms that the earth is spherical is the moon's eclipse. When the Earth comes between the sun and the moon, it casts a shadow on the moon, which appears as a curved shape. This curved shadow is evidence that the Earth is spherical in shape. If the Earth were flat, the shadow would be a straight line. This phenomenon is visible from anywhere on Earth and has been observed by humans for thousands of years. In addition to the lunar eclipse, other evidence that confirms the spherical shape of the Earth includes the fact that ships disappear over the horizon as they sail away and the changing positions of stars in the sky at different latitudes.
