The three brothers

One more answer:

The three brothers live in a house
They look truly different
But if you want see the difference,
Is each one like the other two

The first one is not here, he is just coming home
The second one is also not here, he already went out
Only the third is here, the smallest of the three
Because without him, there wouldn't be the other two

And yet, there's the third one in question
Because he is the first, who turns the second to the third
But if you want to look at him,
Then you will only see on of the other brothers

Now tell me: Are the three maybe one?
Or are they two? Or none at all?
And now, can you tell me their names?
Then you will see three powerful rulers who rule a great empire

No king, no president, can own there kingdom
Because the kingdom they rule, they are that themselves
If you take a look at there kingdom, then maybe you can only see stuff
But if you look closer, you can see you

I think the three brothers are

I think I wrote a riddle a while ago with exactly the same theme/solution (but maybe I was just thinking of this one).
