OP: There is NO Biblical basis for your 'orb' interpretation. Orbs have never been shown to have wheels in them. In pictures, most, if not all, are simply small particles of dust on the lens of the camera. Orbs are Not mentioned in the Bible. And not that God Couldn't or hasn't, but it would be something that could not be denied AS FROM GOD, rather then supposed, guessed at, hoped, or in any other way surmised. You need to remember that God is not about 'display' or 'show', but about Power and Truth.
There are many that claim to have seen 'orbs', but the question needs to be asked: What purpose did they serve...being 'seen'? Holy Spirit is never described as an orb in Scripture; in fact, He is not described in any physical fashion at all, short of a dove (Mt 3:16). Also ask, "What did the view of the 'orbs' cause in the people? Did their focus remain of Jesus?? No...they ooo'ed and ahhh'ed over the orbs...how many, how big, what color. Get the point? Be not decieved!
2 Corinthians 11:3But I am afraid that, as the serpent
deceived Eve by his craftiness, your minds will
be led astray from the simplicity and purity
of devotion to Christ.
Deuteronomy 11:16Beware that your hearts are not
deceived, and that you do not turn away and serve other gods and worship them.
