Bowing in Amida

During the amida we prostrate and rise up at Hashem’s name but during temple times and in heavenly worship we prostrate, bow and fall on our faces at Hashem’s name, why the drastic change? Does not the latter seem more logical and correct?

During temple times, where the shchina (diving presence) was palpably felt, we would prostrate and fall on our faces in sheer awe. However, today in galut (exile) where we don’t feel Hashem’s presence as much, it suffices to bow as a sign of deference and respect without falling completely on our faces.
