Origin of A Far Cry Fromhttps://writingexplained.org/idiom-dictionary/a-far-cry-from
This expression is based on its literal meaning. A far cry originally meant a distance that was too far to call across easily. This means that even if a person were shouting to someone else, it would be hard to hear because they were so far away from each other.
The idea behind the figurative meaning is that two things that are far away are most likely very different from each other.
雲泥の差、月とすっぽん、というところでしょうか。
