Can the Firebase user id change? What I talk about is this, FirebaseAuth.getInstance().getCurrentUser().getUid() If user delete his account like it is described here Manage-users. I was assuming the getUid() id was tied to the E-Mail right, or!?

As said by @user663031, the answer "no" is correct.
To add on to @user663031's answer, I'm working on a project, but I have to switch between the live database and the test database. I created a user (in firebase authentication) in both test & live environment with the same email address & password, however the id's are different.
In order to achieve proper tests in both environments, I had to change id stored in real time database so that it matches the "unchangeable id" in authentication.
