Why does the parent's origin move to the child's origin?

Question

Unity

Hello. Created a 2D project in Unity. I created an empty object, I create a cube next to it. As soon as I put the cube in an empty object in the hierarchy panel (the panel on the left, where all the objects on the stage are shown), the center of the empty object's coordinates moves to the center of the cube's coordinates (that is, its starting coordinate (0, 0, 0) is now in the center of the cube , and not in world coordinates (0, 0, 0). Who knows how to fix it. Through the code, the same garbage.

Answer 1

Hello. I have never run into this problem myself, and the uncles with higher ratings above (or below) this comment are right, but did not answer my question. The problem is solved in such an interesting way (although I don’t understand how it works at all. Okay in the viewport, but through the code it also worked as it should. Really strange)
Solution

Answer 2

The inspector always shows local coordinates - i.e. coordinates relative to the parent object.
Through the code, you can get both local and global coordinates.
There is nothing to fix here.
