YOU SAID:
the world is changing before my eyes
INTO JAPANESE
世界は私の目の前で変化しています
BACK INTO ENGLISH
The world is changing in front of me
INTO JAPANESE
目の前の世界は変わりつつある
BACK INTO ENGLISH
The world in front of us is changing
INTO JAPANESE
私たちの目の前の世界は変化しています
BACK INTO ENGLISH
The world in front of us is changing
That didn't even make that much sense in English.
