YOU SAID:
Some day when we are wiser and the world's older
INTO JAPANESE
私たちが賢くて世界が年をとったいつの日か
BACK INTO ENGLISH
Someday when we are smart and the world is old
INTO JAPANESE
いつか私たちが賢くて世界が古いとき
BACK INTO ENGLISH
Someday when we are smart and the world is old
That didn't even make that much sense in English.
