Why UFO's are big No-No's

I have recently remembered a conversation I once had with my brother when we were teenagers. He stated that he did not see a problem with believing that YHUH and Yahushua were just super-intelligent extra-terrestrial beings that traveled around in UFO's to get their job done. So, can true disciples of Yahushua believe in UFO's? Well, in short, you are looking for trouble if you do. Read the following:

My spouse pointed out, while I was looking for images for this post, the interesting correlation between the decade the UFO's were sighted (60's, 70's etc.), and the level of design of the UFO's over time. The UFO's appear more well designed with the passage of time, correlating with what was being shown in the movies of those eras :-) You can say, at a glance, from the retro design, whether a UFO was sighted in the 60's for example ;-) If the UFO's are being flown by such super-intelligent beings, why do their designs improve at the same rate as ours, and according to our tastes, as shown to us in the media? They are light years ahead of us apparently so why are they so influenced by us here on earth? If we look back to 50 years ago, how unsophisticated do the UFO's of those days look to us now? Why?

Anyway, all I know is that I will not be fooled when Yahushua returns. I know He is not returning in a UFO. There will be the Trump of the Arch Angel and Yahushua himself, with clouds of angels, will descend with a shout - who can miss that? Not to mention that Yahushua tells us:

John:10:27: My sheep hear my voice, and I know them, and they follow me:

All I can say is keep your ears open everyone :-)

Oh, if you are wondering where my brother has ended up with his "creative" thinking - by limiting YHUH, in his mind, to having to travel in a spaceship, logically it was not difficult for him to become a total atheist, but then, more interestingly, he converted to full-blown Hinduism when he got married. From no god to many, many gods and idolatry. See where belief in UFO's can get you?
