YOU SAID:
Life was good and then the fire nation came and everything changed
INTO JAPANESE
人生は良かったとファイアー nation が来た、そしてすべてが変わった
BACK INTO ENGLISH
Life was good and came the fire nation, and everything has changed
INTO JAPANESE
人生は良かったとファイアー nation と来たすべてが変わった
BACK INTO ENGLISH
Life changed everything was good and came with fire nation
That didn't even make that much sense in English.
