The problem with adding "other" in Colossians is that it contradicts all other scriptures saying that ALL things where created by Jesus. So Jesus could not create himself could he ?
Cf. John 1:2; 1:10; 1 Co 8:6; Heb 1:2
In all these verses there is no "other".
If everything was created by Jesus then Jesus was not created. As simple as that...
