YOU SAID:
I am on a chair, on the ground, on the planet Earth
INTO JAPANESE
私は地球上の椅子、地上、地球にいます
BACK INTO ENGLISH
I'm in the chair on earth, on earth, on earth
INTO JAPANESE
私は地球上、地上、地上の椅子にいます
BACK INTO ENGLISH
I'm in a chair on earth, on earth, on earth
INTO JAPANESE
私は地球上、地球上、地球上の椅子にいます
BACK INTO ENGLISH
I'm in a chair on earth, on earth, on earth
That didn't even make that much sense in English.
