Nasa/JPL has regressed some Near Earth orbitors..and hypothesised that they may be remnants of a Moon which broke apart from some tidal force.
Clube and Napier forward the theme of supercomet break up..over periods of 20,000yrs..the fragments simply hamering into worlds as they are vacumned up in gravametric cycles.
The 4 known streams of the Taurid complex..which the Earth transits thru for a full quarter of a year..have been regressed via computer to a singular ident.
Comet Encke part of this debrie stream.
Other candidates exist to cause the Earth to fault under gravametrics...Velikovsky Mythological detective study concerning a wandering Venus..and Mars.
Could their have been another moon..before the one we presently see today?
could there have been 2 or more of varied size?
The records of Emporer Yahu of China record an event where waters were pulled up into the sky..and towered above the mountains..then there was an electric discharge....and the waters collapsed to inundate China for over 100 yrs.
But ya..maybe Opium was the national passtime of the early Dynastic kings...and Confuscious's validation of the event.....some reflection after a pull on the Opium pipe : )
