It seems to me that a "wheel inside a wheel" ultimately goes nowhere...

could be a reference to Ezekiel's Wheel, for which "wheel in the sky" is also a frequently-heard colloquialism.

there are a surprising proportion of otherwise-orthodox Bible believers who are convinced that the "wheel" was a UFO (as best as could be described, given the vastly different frames of reference at the time the Old Testament was written), and the "angels" were aliens.

Angel as aliens...interesting.

Yeah, besides the reference to the wheel inside a wheel which is a common reference to UFOs in ancient times (there is a reference to a wheel inside a wheel in the old testament that is interpreted as a UFO) the whole song speaks to a first encounter with aliens.
