There would appear to be a fundamental flaw in that viewpoint
To wit:
Who is the "we" that will be made immortal?
Is it the ones that are currently alive? Or are you referring also to the ones that have gone before and will come later?
If it is the latter then you have to contend to the dreadful problem of overcrowding - unless you also say "God will provide" which is not how it works - think of the famines that occur - and you have also said this
Does that then refer to the souls of people? I have heard it indicated that some believe that the soul is mortal and perishes at the end of the journey.
The overall picture seems promising - the details leave me confused
The problem of space will literally be answered by "space".
The kingdom of God only begins on Earth.
Biblical scripture specifies that not only the earth, but the entire universe -"the heavens" - were "not formed in vain" but "were formed to be inhabited" (and we do not know if there is anything beyond our universe -but it is also specified that of the
increase of his government and peace there will be no end).
Though it is not widely believed due to taking some verses out of the entire context (God had his word written "line upon line, precept upon precept, here a little, there a little"), scripture also states "As in Adam all die, even so in Christ will all be made alive". It also states that those whose works were not good "shall be saved, yet so as by fire". All will be made alive "but every man in his own order". There is a first resurrection -those in the first resurrection becoming the government of God as immortals on Earth for the first thousand years -and "the rest of the dead" will be resurrected to the judgment after the thousand years -which is anot all bad. Some whose works were generally good (but were not called to the first resurrection) will be made immortal -and others will "have their part in the lake of fire" -which is actually a final ultimatum and purification. ("For he is like a refiner's fire")
The term soul can be confusing. Technically, the word translated "soul" in the bible refers to the entire creature -and is even used to describe animals.
The "spirit in man" -the part which makes them who they are (the software, if you will) -returns to God and the body returns to dust.
At that point, one is essentially "asleep" -until put within a body again -eventually a very powerful and capable body which is not bound to the earth as are our present bodies.
(Phillipians 3)
from whence also we look for the Saviour, the Lord Jesus Christ:
21Who 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.
(2 Cor 5)
18I consider that our present sufferings are not comparable to the glory that will be revealed in us.
19The creation waits in eager expectation for the revelation of the sons of God.
20For the creation was subjected to futility, not by its own will, but because of the One who subjected it, in hope
21that the creation itself will be set free from its bondage to decay and brought into the glorious freedom of the children of God.
22We know that the whole creation has been groaning together in the pains of childbirth until the present time.
23Not only that, but we ourselves, who have the firstfruits of the Spirit, groan inwardly as we wait eagerly for our adoption as sons, the redemption of our bodies.
24For in this hope we were saved; but hope that is seen is no hope at all. Who hopes for what he can already see?
25But if we hope for what we do not yet see, we wait for it patiently.
(John 3)
…6Flesh is born of flesh, but spirit is born of the Spirit. 7
Do not be amazed that I said,‘You must be born again.’ 8The wind blows where it wishes. You hear its sound, but you do not know where it comes from or where it is going. So it is with everyone born of the Spirit.”…
