Having said that, I'm not sure how you're making a connection between this and the orbs.
The point I'm trying to make, is always keep God's Word as the Measure of all things. Don't be deceived by manifestations that may possibly originate from that other dimension, like UFOs, orbs, little green men with big eyes, etc. So that's not denying that such things can exist, it's about keeping to what God's Word shows about them. The vehicle Ezekiel saw had God's throne upon it, so that reveals what? It reveals that not all those vehicles of that other dimension are of the devil. It's kind of like cars in our world; there's both good people and bad people driving cars. Possibly the same thing in that other dimension with heavenly vehicles.
I reject the idea of aliens, period. However, there has been quite a bit of testimony about some who claim aliens are sampling human DNA in order to create hybrids. Now that may not be too far fetched, because of Genesis 6 about the angels which left their original estate and abode, and took wives of the flesh daughters of Adam, and produced the giant hybrid race which God commanded to be destroyed. But that wouldn't be actual aliens doing that DNA hybrid thing, it would still point to Satan's angels doing that.
What I'm getting at, is that I believe Satan's workers on earth in the past century have been slowly conditioning the world to accept the coming of Satan and his angels when the war of Revelation 12:7-9 happens at the end of this world, and try to claim those are benefactor aliens from another galaxy having come to help the human race out of the mess this world is in. But they will only be the tip of the iceberg, because when Satan comes with them, or is revealed to the world as God, they will use to that explain everything, but the whole show will just be one huge HO-AX. Don't believe it.
