Since you asked, let try this in another way of thinking.
Alien? What is an Alien? Something that is foreign to "Earth"? Something that habitates a place other than "Earth"?
What are the Sons of GOD? Something that is foreign to "Earth"? Something that Habitates a place other than "Earth"?
How can we be certain? Lets look at the account of the fall, covered in Genesis 6.
6:2 That the sons of God saw the daughters of men that they
were fair; and they took them wives of all which they chose.
6:3 And the LORD said, My spirit shall not always strive with
man, for that he also is flesh: yet his days shall be an
hundred and twenty years.
6:4 There were giants in the earth in those days; and also after
that, when the sons of God came in unto the daughters of men,
and they bare children to them, the same became mighty men
which were of old, men of renown.
Now this defines what "SOME" of the Sons of GOD had been doing, and who they where doing, and what all that doing produced. This example is to
indicate the Sons of GOD had come to Earth, since it is very clear, the Daughters of man did not go to the Heavens. The balance of this Chapter covers
where these problems occured and how GOD intended to correct it.
We see in the following the fact that the Sons of GOD came to Earth and left their place of Habitation to do some doing, as noted above.
Jude
1:5 I will therefore put you in remembrance, though ye once knew this, how that the Lord, having saved the people out of the land of Egypt,
afterward destroyed them that believed not.
1:6 And the angels which kept not their first estate, but left their own habitation, he hath reserved in everlasting chains under darkness unto the
judgment of the great day.
1:7 Even as Sodom and Gomorrha, and the cities about them in like manner, giving themselves over to fornication, and going after strange flesh, are
set forth for an example, suffering the vengeance of eternal fire.
Are you seeing some familiar events yet.
Aliens coming to Earth, taking women and creating Hybrid Creatures.
Does this sound like what the Sumerians discussed in Ancient texts?
Does this sound like Greek and Roman Mythology?
or
Does this sound like anything you may have recently seen on T.V.? How about the seires
V for an example. How about George Noory on Coast 2
Coast at least twice a week.
These events noted in the Bible are events which are occuring once again today.
We are even forewarned that this would occur, right after the Parable of the Fig Tree, (Israel reborn)
Luke 17
26 And as it was in the days of Noe, so shall it be also in the days of the Son of man.
27 They did eat, they drank, they married wives, they were given in marriage, until the day that Noe entered into the ark, and the flood came, and
destroyed them all.
As it was in the Days of Noah, so shall it be in the days.....
What Days? The End Day's, after Israel is Reborn. Funny how the "Alien" Encounters increased and became "Noticable" after 1949. Strange isn't
it.
We can even take another source, Biblical in some circles and see what took place.
Enoch 6 thru 10
VI-XI. The Fall of the Angels: the Demoralisation of Mankind: the Intercession of the Angels on behalf of Mankind. The Dooms pronounced by God
on the Angels: the Messianic Kingdom (a Noah fragment).
CHAPTER VI.
1. And it came to pass when the children of men had multiplied that in those days were born unto them beautiful and comely daughters. 2. And the
angels, the children of the heaven, saw and lusted after them, and said to one another: 'Come, let us choose us wives from among the children of men
and beget us children.' 3. And Semjâzâ, who was their leader, said unto them: 'I fear ye will not indeed agree to do this deed, and I alone shall
have to pay the penalty of a great sin.' 4. And they all answered him and said: 'Let us all swear an oath, and all bind ourselves by mutual
imprecations not to abandon this plan but to do this thing.' 5. Then sware they all together and bound themselves by mutual imprecations upon it. 6.
And they were in all two hundred; who descended ⌈in the days⌉ of Jared on the summit of Mount Hermon, and they called it Mount Hermon, because
they had sworn and bound themselves by mutual imprecations upon it.
The balance of these 4 Chapters is well worth the reading, especially if you would actually like to know what these "Aliens" actually are. They were
doing exactly what the "Alien" events today are doing and will do. There is NOTHING NEW under the SUN.
Now, you spoke about the 8th day, and this creation occuring. I will suggest this event is older than that. MUCH OLDER.
What you have proposed, is something created in a period of Time between Genesis 1:1 and Genesis 1:2
As is clearly covered within the following
Chronology of Creation in the Bible... it
doesn't start in Genesis! there is a large period of time that is actually occuring between the first two verses of Chapter 1 of Genesis.
It would be "within this period" that your ETs/Aliens/Sons of GOD would have been designed.
I have gone to this extent to offer you various views that should be considered and reviewed when faced with questions such as you have asked.
Your Question itself, is a great question. It is something that SHOULD BE DISCUSSED openly, freely, and collectively.
I have presented some things you MAY NOT have considered previously, and trust this would assist you in settling this question for yourself. There are
many more examples, and actually several TOPICs Specifically directed towards these thoughts.
In closing I would suggest, the only thing that may have been created on the 8th day, was The MAN, Adam, the one to Till the Ground, and I only say
this, because Adam is created after the 7th day, the Day of rest.
Good luck in your search for answers.
