The Earth is a perfect sphere. Stars and constellations do not rise or set. The Sun rises exactly in the east and sets exactly in the west every day. There are an exact number of days in the year.
Water goes down the drain in different directions in the northern and southern hemispheres.
The Earth is at the center of the Solar System. We experience seasons because of the Earth's changing distance from the Sun. Everyone on the Earth shares the same seasons on the same dates. North, south, east, and west are actual places on the Earth. All the stars in a constellation are near one another.
