This is our Father's world. And the world knows it; it just doesn't want to admit it. That inborn curiosity is communicated by Solomon's statement under inspiration in Ecclesiastes 3:11:
He hath made every thing beautiful in his time: also he hath set the world in their heart, so that no man can find out the work that God maketh from the beginning to the end.
God has set the world in their heart. They have an itch that they can't scratch, even while they are admitting that everything is just fine---shirt tail pulled out, belt loosened, reaching everywhere for that itch. But everything's fine.
The above is also why the world can't just ignore genuine Christianity. It must savage it. Because the world really does know. The only ignorance is a purposeful kind. It is all rebellion.
Let me get to the point of my post. Aliens. Two parts about them.
Aliens a Good Explanation for the Rapture
Aliens. There aren't any. If we evolved, yes. But we didn't. Aliens, however, would be a great explanation for the apocalypse. It is so convenient. I know you've thought of this, but think about it again.
Why are there so many television shows being made about apocalyptic events by those who don't profess to believe the Bible? Feature films and television series all over the place looking toward the end of everything with aliens the cause. It reminds me of the talking points of the religious leaders about Jesus. They knew He was supernatural and they couldn't say He was God, so He had to be the other side---Beelzebub. By process of elimination, they went with Satan. In this case, they foresee some end to everything. It's instinctive to mankind---he sees the arc of history on the backside toward destruction, and since He can't admit that it will all conclude with God, He chooses door number two. If not a meteorite, then aliens.
Aliens are a fitting set-up for Satan to keep people zombie-like through the first half of the tribulation period. Where did those people go? I don't know, but maybe it's just what we suspected---aliens. Maybe. It sounds feasible to someone who is accustomed to shutting out what's true. And we live in a world that sees not choosing any particular explanation as the most scholarly. If you've got several options, then you are open and nuanced. Could be aliens? Sure. I don't know. As good an explanation as any, so I'm sticking with it until a better one comes along.
You don't have to believe anything. You are free to believe what you want. If you've got options, then you've got an alternative to what's true. And the options still leave you in charge. So aliens it is.
The shows and books have trained the imaginations for aliens as an alternative. People who have already rejected Christ won't find the mental, emotional, and volitional slide over to the alien explanation as too difficult. Even those with a lesser, non-saving brand of Christianity could hang on to it as a possible reason. They have already bonded with the world enough not to turn from their way, so they could entertain aliens until further notice.
The aliens might be studying these people they've taken in lieu of future plans. The aliens may need them for organ harvesting. Maybe they want them for some celestial zoo, like doing a planetary safari.
Feel free to laugh. But you know I'm right. There is just way too much consideration of these plot lines all over simply to dismiss it. And if you are an amillennial, then your eschatology requires it to be a joke.
Aliens a Good Explanation for the Tribulation
When things are going seriously bad during the Great Tribulation, it will be difficult to stick with ordinary explanations. Aliens could provide a nice alibi. It's your story and you're stickin' with it. If not that, then global warming. But aliens might suffice. With the carnage all about you, you might not want to think of the eternal damnation coming up next, so focus on aliens like the last leg of a slow, painful jog. You wish.
We don't have cable or an antennae, so I don't know all the shows and movies out there, but I looked at the list of television renewed or cancelled for 2012 and these look like they fit the bill: The Event, Fringe, V, Supernatural, Smallville. We've already had X-Files, Star Trek (and all the spin-offs), The 4400, Alien Nation, Babylon 5, and more (so many that there are lists under each letter of the alphabet). Feature Films (you can find at Wikipedia) just the last two years: Cowboys and Aliens, Skyline, Battle: Los Angeles, Transformers, Chronicles of Riddick, and many more and many more to come.
That stuff happening from above? Aliens. Gotta be. That thought could be something to grab a hold of.
