why is that visible light can pass through transparent objects but not opaque ones?

I believe, the magic words here are "band gap". All transparent materials are dielectrics, which means they have a band gap and cannot absorb photons with certain frequencies. Metals, on the other hand, have no band gap and free electrons are excited easily by visible light.

The arrangement of atoms in transparent material permit the frequencies of visible light to weave a path through.

It must be because of the structure of the molecules of the transparent substance permits light to pass by without hitting any part of the substance.

It's true by definition.

It is in nature to do that.
