Before, we called the direction of sunrise east, of sunset west; now we say that the sun is a fixed star?

Question

Why do we continue to base on that wrong concept of the moving sun to make distinction between east and west? If I say I am residing in the west, how can you tell I am exactly on what part of the world?
It seems that, I am living in the west of the countries which started to see the fixed light of the sun over 23 hours before mine.
And it seems that we don't follow any truth, but we only follow conventions. But many people keep on telling that truth is based on what they see like the sun (which they can never touch!). Because conventions are not eternal truth (like national constitutions), so we have to rewrite them more and more often. And finally, we base on what truth to act as dictators (who claim to hold the truth!) or as supporters of a dictator (who claim to follow the truth!)? If there were no truth, how would we seek consensus to make new conventions? If we could not make new conventions to suit this global time, should intelligent beings accept to live under anarchy?

Answer 1

Let us begin with absolute Truth, since this is important to you. Seen any lately?

Answer 2

The Earth turns, that's all. It is perfectly reasonable to say the sun is in the east when it rises, and in the west when it sets. The reference point is a direction on the Earth, not which way the sun's moving. The sun does move though. It is not "fixed." It rotates around the galactic core. Once every 200 million years, the sun completes one orbit.

Answer 3

We all understand that the earth revolves around the sun and rotates around its axis. We learned that in elementary school.

By convention, people have agreed which way is west or east and what locations are considered west or east. This is arbitrary, but it simplifes our description of direction
