“8 As for their rims, they were so high they were awesome; and their rims were full of eyes, all around the four of them. 19 When the living creatures went, the wheels went beside them; and when the living creatures were lifted up from the earth, the wheels were lifted up.”
The “eyes” could be lights on the craft. The wheels could be landing gear? The crafts could be some high-tech (UFO) drones. The inter-dimensional aspect could just mean they require the use of wormholes to travel back and forth from our dimension to theirs. I’m a lifelong SciFi fan, so this subject is fascinating (as Spock would say) to me.
Or sensors - it could just mean their ability to see in all directions and thus move in all directions.... but I don’t think this described a mechanical entity. At least not from my Christian perspective. A non Christian/Jewish observer might think the early Jews were describing a spaceship with the limited knowledge in machinery at that time. Hence the recent conclusion from things like the show Ancient Aliens.
Dimensional travel, sure. From the spiritual dimension that exists but we can’t detect or see with our current instruments. I do believe we agree on dimensional travel ;)
