Does „the truth“ exist?

There are several truths. The truth what you think is right and the „other truth“ where the others think is true. There are several perspectives:

Person A says that the stone is flat. Person B says that the stone is Bumpy (auf deutsch:hubbelig). So the opposite. But who is right?They only see their own view and not the other one. They blame each other. But what would happen when they change places? Person A would would say that the stone is bumpy and will be confused. Person B too.
In our „everyday life“ is it the same. We stand face to face each other like Person A and B. We blame us ourself. But why do we not stand next to each other? That would be easier or not? Why do we have to blame others? And who is right? All these questions..
Have a nice evening:)
