Blender Mirror Problem

I have a very strange problem and I couldn’t solve it. The mirror does not copy the object to the opposite side. He copies it to his side.
It is not copied when there is only one cube, I added another object and marked it, it is not copied again.

you have to move the origins of the cube to 3D cursor first then add mirror modifier.

btw your mirror axis is wrong, try check the y axis and uncheck the x axis

Thanks to you, I realized the simple solution in front of my eyes. While trying the solution, I did not click Y axis and click Z axis, I keep making such simple mistakes.
