Why is the globe tilted at 23.5 degrees? Please give me some advice!

1. Because the earth is also tilted like that. 2. When you look at the globe from a relatively horizontal angle, you are looking at the earth from the perspective of the sun. 3. It is determined by the ecliptic angle. 4. Because the Earth is tilted relative to the orbital plane around the sun. 5. Because the Earth’s rotation axis in the Earth’s orbit is tilted. 6. Because the Earth’s axis is tilted by 23 degrees and 26 minutes. 7. Because the sun is incident horizontally, and the plane of the earth is at a certain angle from it. 8. It is believed that the earth itself is tilted 23.5 degrees in space, so the globe also imitates this state. This understanding is wrong. When considering the position, angle, speed, etc. of an object, there must be a frame of reference. In the universe, there is no directionality of up, down, left, right, and back. Only after a certain reference system is determined can the position of an object be determined. To say that the Earth's rotation axis is tilted is based on the Earth-Sun system as the reference system. 9. This is because the angle between the ecliptic and the equator is 23 degrees 27. The globe is to simulate the actual state of the earth.
