It was again, my bad...
Although I think it was more accurate than "Chariots of the Gods", given that I don't ascribe a capital "G" to the term "god"...
Having never seen a "chariot of fire" up close, the term is just as inter-changeable as "u.f.o.", although "object of light" would seem even more accurate.
Even today, with access to global communications, websites from NASA and other astronomical and meteorological scientists as well as Google or Wik - ignorant people still ascribe the supernatural to meteorological phenomena such as comets, metoers, sun dogs, eclipses etc that they have never seen before and have no personal (let alone scientific) explanation for. This does not mean that these phenomena are unexplainable, merely that the observer couldn't explain it.
Now imagine how ignorant the general public was 100s or 1000s of years ago. Same phenomena, even less explanation for it. Consider also that religions have shown that they are quite willing to exploit such "unexplainable" phenomena for there own purposes, even now the Roman Catholic church support the idea of miracles for their own purposes.
Ages ago, you might have overheard a conversation something like this,
Rube: Wow, did you see the fireball that shot across the sky last night Oh Great and Holy Priest?
OGaHP: You mean the Flaming Chariot of God streaking across the Heavens?
Rube: Chariot?
OGaHP: Only those unworthy would not have been able to see the Flaming Chariot of God.
Rube: Oh, THAT chariot. The two wheeled one.
OGaHP: Three wheeled...
Rube: Oh, right, yes, three wheeled chariot, pulled by four horse...
OGaHP: Two horses
Rube: Right, right, TWO jet black horses.... I remember now, and...
OGaHP: Golden horses.
Rube: Yes, yes, two golden horses pulling a golden chariot
OGaHP: FLAMING, golden chariot
Rube: Of course, of course - goes without saying it was a FLAMING, golden chariot that would be carrying God.
OGaHP: ... and his angels
Rube: Angels, right. God was so big I missed them standing behin...
OGaHP: ... on either...
Rube: ... on either side of god. Holding their flaming, er.....spears?
OGaHP: ...swords..
Rube: Right, flaminnnng..
OGaHP: yes...
Rube: flaming swords of righteousness.
OGaHP: You are blessed my child.
Rube: Should I go out and sacrifice a goat to our god?
OGaHP: Oh, coin is fine. Just leave it with me and I'll make sure god gets it.
Rube: Riiighhhttt, would 10 be
OGaHP: 20 would be more righteous
Rube: 20. Ooookayyy...
OGaHP: And don't forget, the church is tax deductible, so when the soldiers come for your first born son, you can defer that until next year.
