Incorrect Statement:
- The Earth is flat.

Explanation:
The statement that "The Earth is flat" is incorrect. This idea has been debunked for centuries through various scientific observations and evidence.
1. Scientific Evidence:
- The Earth is a sphere, as proven by multiple scientific disciplines such as astronomy, geology, and physics.
- Observations like the curvature of the Earth's shadow during a lunar eclipse, the way ships disappear over the horizon, and the shape of the Earth's shadow on the moon during a lunar eclipse all point to a spherical Earth.
2. Satellite Imagery:
- Satellite images show a clear view of the Earth as a round object, further supporting the fact that the Earth is not flat.
3. Space Exploration:
- Astronauts and space missions have provided direct evidence of the Earth's spherical shape through photographs and videos taken from space.
4. Historical Evidence:
- Ancient civilizations like the Greeks were able to deduce the Earth's spherical shape through observations like the changing positions of stars as one moves north or south.
In conclusion, the statement that the Earth is flat is incorrect and goes against a plethora of scientific evidence and observations. The overwhelming consensus in the scientific community is that the Earth is indeed a sphere.
