an empty vacuum that houses our galaxy and many others.
What pressing need? There is no religion that has proved anything that isn't open to interpretation.
Angels/spirits are spoken of in scripture -as well as "living creatures" which are apparently not human in at least the temple of God.
It is also written that eye has not seen -nor ear heard -what awaits us.
As far as I know, it is not specified in the bible that there are no other "children of God" -similar to our physical composition -on other planets.
However, it is written that the government of the entire earth -and then universe -perhaps beyond -will be headquartered on earth -beginning with the thousand year reign of Christ and those humans made immortal who will then rule under him.
Earth is unique in that respect according to scripture, and it is at least suggested that the Earth is unique thus far in its state -and the children of God from Earth will eventually oversee the ordering of the universe -having been given bodies which will allow power over even cosmic events.
(Pardon no book/chapter/verse in the following bible quotes -not used to iPad)
****************
Who shall change our vile body, that it may be fashioned like unto his glorious body, according to the working whereby he is able even to subdue all things unto himself.
For the creation was subjected to futility, not willingly, but because of Him who subjected it, in hope
21that the creation itself also will be set free from its slavery to corruption into the freedom of the glory of the children of God.22For we know that the whole creation groans and suffers the pains of childbirth together until now.…
For thus saith the LORD
that created the heavens; God himself that formed the earth and made it; he hath established it,
he created it not in vain, he formed it to be inhabited: I am the LORD; and there is none else.
Through faith we understand that
the worlds were framed by the word of God, so that things which are seen were not made of things which do appear.

6For a child will be born to us, a son will be given to us; And the government will rest on His shoulders; And His name will be called Wonderful Counselor, Mighty God, Eternal Father, Prince of Peace.
7There will be no end to the increase of His government or of peace, On the throne of David and over his kingdom, To establish it and to uphold it with justice and righteousness From then on and forevermore. The zeal of the LORD of hosts will accomplish this.
2And I saw the holy city, new Jerusalem, coming down out of heaven from God, made ready as a bride adorned for her husband.
3And I heard a loud voice from the throne, saying, "
Behold, the tabernacle of God is among men, and He will dwell among them, and they shall be His people, and God Himself will be among them,
4and He will wipe away every tear from their eyes; and there will no longer be any death; there will no longer be any mourning, or crying, or pain; the first things have passed away."…
Blessed and holy is the one who has a part in the first resurrection; over these the second death has no power, but they will be priests of God and of Christ and will reign with Him for a thousand years.
*******************
The thousand years is the time between the first and second resurrections (those in Christ at the first -the rest of the dead to judgment/purification at the second [when some will be saved "yet so as by fire]).
Though a thousand years is specified for those who reign with him, his reign will be eternal -and those who reign with him will be part of his government eternally (technically, everyone/everything will be part of his government) in some capacity.
