Actually I came across some interesting information the other day which might pertain to this. According to scientists, the solar system is in a "superbubble" which is a remnant of this space being earlier occupied by an O/B star pair. This is referred to as the "Local Bubble"

Other "superbubbles" occur in BOTH Orion AND Ophiuchus. (Recall these are opposite each other in the sky. Oxygen has been detected in both areas as well) .
ANOTHER "superbubble" is in the Large Magellanic Cloud, which is a satellite galaxy to our own. There is a stream of energy/particles originating from the LMC that is flowing into the Milky Way.. AND if I am not mistaken, this stream crosses through the galactic plane very close to where our solar system is right now.

Exoplanet found… from another galaxy!!
How Milky Way’s Spiral Arms Formed
And some visuals:

I think this constitutes decent evidence that our solar system is not the first creation to take place in this space. So it wouldn't surprise me if there were remnants of that evolutionary octave still present here/now.

Quote:At any rate, astronomers think the Large Magellanic Cloud may have been closer to Earth once upon a time as it drifted past the Milky Way a billion years ago.Also see these articles:
A trail of gas and dust, which astronomers call the Magellanic Stream, extends across our sky. The Magellanic Stream probably is matter ripped away from the Large Magellanic Cloud by Milky Way gravity.
It's not clear whether the Magellanic Clouds are satellite galaxies of the Milky Way, forever circling us, or simply passers-by on a one-time chance encounter as they make their way through the Universe.
