Isn't it also possible that God created life throughout the universe, and extraterrestrial aliens are just fellow sinners?
There are no extra terrestrial aliens, there are only angels, fallen and unfallen, and both use technology.
And you know this with such certainty, how? And no, you can't say "because the Bible tells me so" since that's the same argument human beings used to explain why other human beings were creatures of Satan as well.
The falling away comes first so that the Antichrist can rise, and he won't be representing former religions, such as Christianity, he is the Christ of a new god, a god of forces, a new god unknown to mankind, and he will claim its power makes him God:
This is actually what Hal Lindsey has adopted in recent years. Don't you find it odd that ANY Orthodox Christian would agree with the guy who wrote The Late Great Planet Earth?
Besides, even if what you say IS true, I think most of us scifi fans are going to be safe since Stargate has prepared us for the day when the Goa'uld return via Ezekiel's wheel and try to enslave us by claiming to be gods! So I'm pretty confident when Apophis or the Ori come to trick us, at least us SG1 fans won't be deceived. Thank you Daniel Jackson! 
Okay enough silliness, but I can't help it, you've brought out the scifi geek in me!
I actually do find your hypothesis fascinating, I mean I love all this kind of stuff, Chariots of the gods, and all those books. Very cool stuff. I don't think it's true, but I love talking about it. I even wrote a story about this stuff one time, back in my Protestant days, but I also think if there are aliens (and there probably are) it's un-Christian to just assume they are instruments of Satan; like I said, that's what Christians said about the Native people of the new world too, of course we now know better.
Because my posts are moderated, Its hard to carry on a discussion.
My hypothesis is not bizarre...hopefully the following proves that...as you get towards the end, it discusses heaven and earth, the scriptural teaching about it, and the nature of angels.
I repeat, I do NOT believe ufo aliens exist...I believe fallen angels who will pretend to be ufo aliens, exist.
peace
Someone will say "this is Bizarre."But should I accept the usual view in the commentaries, that the last week of the 70 weeks, occurs centuries later, is that less bizarre?
I can't agree with the commentaries on the seventy weeks, the plain reading is these are 70 contiguous weeks segments of which are characterized by unique events.
24 Seventy weeks are determined (נֶחְתַּךְ 2852) upon thy people and upon thy holy city, to finish the transgression, and to make an end of sins, and to make reconciliation for iniquity, and to bring in everlasting righteousness, and to seal up the vision and prophecy, and to anoint the most Holy. (Dan 9:24 KJV)The 70 weeks are contiguous as these were "cut out" as a specific length of time, that is how they were "determined." They weren't "cut out" separately or in separate pieces.
26 And after threescore and two weeks shall Messiah be cut off, but not for himself: (Dan 9:26 KJV)
AFTER the 62 weeks, which is after the 7 = 70 weeks."And After", conjunctive preposition, its a segment AFTER those just listed.
The Messiah is cut off in the Seventieth week ("after" 7+62) and His Death ushered in the New Covenant which fulfilled all the goals listed in v. 24, "To finish the transgression (Rom 4:15), To make an end of sins (Rom 6:22; Heb 9:26)), To make reconciliation for iniquity (2 Cor 5:18), To bring in everlasting righteousness (Rom 3:21f), To seal up vision and prophecy (Luk 16:16; Mat. 5:17; Acts 10:43), And to anoint the Most Holy (Luk 4:18 cp Joh. 2:18ff)." Therefore its fitting Christ have the entire 70th week all to Himself. Verse division is not inspired, verse 26 should have ended with the advent of the New Covenant in Christ's blood.
So Dan 9:26a has the Messiah fulfilling all the goals of Dan 9:24 with His death. 26b refers to the Titus destroying the Temple in AD 70, and 26c the continuing desolation that culminated in the Jews being driven out of Palestine by Hadrian about AD 132.
While Dan 9:27 can be rendered with the personal pronoun "he" making it refer to the "prince who is to come," it is NOT required:
LXT Daniel 9:27 καὶ δυναστεύσει ἡ διαθήκη εἰς πολλούς (Dan 9:27 LXT)
LXE Daniel 9:27 And one week shall establish the covenant with many: and in the midst of the week my sacrifice and drink-offering shall be taken away: and on the temple shall be the abomination of desolations; and at the end of time an end shall be put to the desolation. (Dan 9:27 LXE)
BBE Daniel 9:27 And a strong order will be sent out against the great number for one week; and so for half of the week the offering and the meal offering will come to an end; and in its place will be an unclean thing causing fear; till the destruction which has been fixed is let loose on him who has made waste. (Dan 9:27 BBE)
Grammatically the pronoun could be left out.
The "prophetic telescoping" is NOT with the Temple in Jerusalem and a rebuilt Temple in the end time, because Gabriel separates 70 AD and the end time, inserting the "times of the Gentiles": "And they will fall by the edge of the sword, and be led away captive into all nations. And Jerusalem will be trampled by Gentiles until the times of the Gentiles are fulfilled. (Luk 21:24 NKJ)
So we must look for a time period that contains the identifying 3 1/2 years, and that occurs after the times of the Gentiles are fulfilled:
NKJ Daniel 12:7 Then I heard the man clothed in linen, who was above the waters of the river, when he held up his right hand and his left hand to heaven, and swore by Him who lives forever, that it shall be for a time, times, and half a time; and when the power of the holy people has been completely shattered, all these things shall be finished.
NKJ Revelation 12:6 Then the woman fled into the wilderness, where she has a place prepared by God, that they should feed her there one thousand two hundred and sixty days (Rev 12:6 NKJ)
Critically speaking, this view is parsimonous, conforming to the details of the text, while the commentaries, by separating the weeks, make it impossible the destruction of the temple, and Christ's advent, be in the same week.
Therefore I might characterize the "accepted views" on this, BIZARRE.
Gabriel keeps talking however, he continues prophesying about what happens after the 70 weeks, that the Temple will be destroyed, and later, the Jews led captive into all the nations.
Therefore the week in the book of Revelation, is NOT part of the 70 weeks, and it can be separated from them by thousands of years.
But do the commentaries exegete this critically...no, they all put the 70th week in the end time.
AND THAT IS BIZARRE, as Daniel's usage of weeks doesn't allow it:
If we study Daniel's use of "weeks" (7620 שָׁבוּעַ, lit., "sevens"), he
clearly means contiguous weeks. "Seven weeks" and "threescore and two weeks" are misleading if they don't refer to two units of time, one totaling 7 adjoining weeks, the other also 62 contiguous weeks. Dan 9:25 Know therefore and understand, that from the going forth of the commandment to restore and to build Jerusalem unto the Messiah the Prince shall be seven weeks(7620), and threescore and two weeks(7620): the street shall be built again, and the wall, even in troublous times. (KJV)
Here we see one week divided into segments where different events occur, but not implying these are separate in a group of more than one literal week: Dan 9:27 And he shall confirm the covenant with many for one week(7620): and in the midst of the week(7620) he shall cause the sacrifice and the oblation to cease, and for the overspreading of abominations he shall make it desolate, even until the consummation, and that determined shall be poured upon the desolate. (KJV)
Daniels' mourning occurs in three weeks total, not three divided weeks in a longer period of time. Dan 10:2 In those days I Daniel was mourning three full weeks(7620). (KJV)
Dan 10:3 I ate no pleasant bread, neither came flesh nor wine in my mouth, neither did I anoint myself at all, till three whole weeks(7620) were fulfilled. (KJV)
Its impossible we divide these "weeks", they are contiguous as seen by Daniels' usage of "weeks."
It is expected Bible prophecy become clearer as we approach its fulfillment...
I submit to you, my interpretation fits scripture perfectly, and while it is different, its certainly no more BIZARRE than what went before it.
To ignore Satan's work in the world, the "mystery (secret) of lawlessness" inspiring rebellion against God's Word of truth, via spiritism (charismania, new age, ufo), to believe THOSE events are not predicted in God's Word of truth, is "bizarre", in contrast to my sound exposition of these things.
Yes, to people our age, they seem bizarre, but 80% of the public now believes there is something to UFOs...those of us who accept the Bible, are now the "fringe."
It should be recalled how inconsistent you are labeling this bizzare, when you fully accept angels as a race of beings who are not "terrestrial."
I argue the church has misunderstood the scriptures about angels, she has accepted incorrect Greek philosophical views about reality, that prevent her from seeing this correctly.
Scripture says there are two realms of existence, one is the MEROS (partial), the other the TELEIOS (complete) 1 Cor 13:10. These are alternate realities....and the inhabitants of both are physical...otherwise how could Jesus sit on His throne, physically, or Moses and Elijah and Enoch, be there also?
Consider the resurrection appearances of Christ, He enters and leaves our MEROS, at will:[/i]
9 And when he had spoken these things, while they beheld, he was taken up; and a cloud received him out of their sight.
10 And while they looked stedfastly toward heaven as he went up, behold, two men stood by them in white apparel;
11 Which also said, Ye men of Galilee, why stand ye gazing up into heaven? this same Jesus, which is taken up from you into heaven, shall so come in like manner as ye have seen him go into heaven. (Act 1:9-11 KJV)
KJV John 20:19 Then the same day at evening, being the first day of the week, when the doors were shut where the disciples were assembled for fear of the Jews, came Jesus and stood in the midst, and saith unto them, Peace be unto you.
(Joh 20:19 KJV)
Christ didn't ooze through the locked door or walls like a spirit, He "stood in the midst", that is, appeared in our MEROS, physically.
The transfiguration wasn't a dream, it was a coming of the TELEIOS with power, intersecting our MEROS:
And he said unto them, Verily I say unto you, That there be some of them that stand here, which shall not taste of death,
till they have seen the kingdom of God come with power.
2 And after six days Jesus taketh with him Peter, and James, and John, and leadeth them up into an high mountain apart by themselves: and he was transfigured before them.
3 And his raiment became shining, exceeding white as snow; so as no fuller on earth can white them.
4 And there appeared unto them Elias with Moses: and they were talking with Jesus. (Mar 9:1-4 KJV)
Clearly the idea angels are spirits (sometimes) in our realm, does not prevent they are physical in their realm and can be so in ours (Gen c. 18-19)...to say otherwise is to deny the teaching of scripture.
Therefore, that fallen angels might pretend to be ufo aliens, and proclaim God doesn't exist, is not a bizarre concept...in fact, given the data, it would be bizarre he not do it, given how well that would work for his Antichrist and his new religion...make all previous religions, obsolete as it were, in the minds of the unsaved.
But the elect won't be deceived.KJV Matthew 24:24 For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect.
(Mat 24:24 KJV)
