Hello
@quietthinker,
While you have a good assessment concerning Adam and Eve. It does seem that you have miss the intent of the question that was at hand.
I'll answer your questions now.
Can life exist forever without God?
Would he maintain at state of misery forever?
If he did then what sort of a being is he?
I believe Yahavah, gives people souls. When they are created in the womb, they are given the ability to in the end, "breathe life within, from the open air out of the womb." While I do believe there is life being created within the womb, a soul is there, but is finalized upon coming out and a fully developed child is formed. Sometimes there is deformations and other issues, perhaps a baby comes out with the umbilical cord wrapped around the baby's neck.
God gave all people the ability to be granted a soul, a mind/will/emotions. There is misery that comes and goes through life, and sometimes that misery could be the agitation from a defect: say a stroke happens and you barely have to use your arm and hand but you can use it just very little. And accident happens and you lose your hand, or you lose your arm. That can be miserable for people. There are emotions and relationship troubles like you mentioned etcetera.
What I find amazing is that people who claim the title of "believer" does believe that at the end of life, a person is finalized into non-existence. That looks like that case in the very first start of the Old Testament. Where did Adam and Eve go? What about Enoch? - "who in my opinion died in his sleep."
It seems that people forget that Yahavah will resurrect all human beings, good or evil, and given them all conditional bodies upon their resurrection suited for them, whether it is condemned or of life, or a better resurrection than the normal and it seems to me, that it's fortold of a place where those people who choose to not to have God in their life, are outside the kingdom.
Are those people outside the kingdom miserable?
Would you say that they are miserable?
What if they are just fine doing what they will without God?
It is perceived a lake of fire which comes from God, and the Lamb and his angels are founded within this fire that purges away the darkness, of perhaps those who are outside, and those from within perhaps help them come to the truth even in the afterlife...
So does God want to retain, or restrain people from getting to his presence in the afterlife? I don't think so, does he desire for those outside to come to the truth just as much as he desires for people today in this life to come to truth? I would say Yes. There is a kingdom which 12 gates surround it and the gates of the kingdom never close. Why? What purpose?
If everyone goes back to non-existence especially non believers, there is no reason to have an outside portion of the Kingdom. I believe Yahavah is a good God, who allows people to have choice, and allows the ability to make the choice just like adam and eve.
Eat from the tree of life, or the knowledge of good and evil, that choice is upon all individuals.
I don't get were people feel they are so special they are "chosen by God" now in the context of the bible and that day in age, I do see where it is that it was possible, but in this day in age, with everything being completed and satan, the beast, and sins being paid for and taken care of and the Lord getting his bride and restoring all things back to the choice of Adam and Eve...
It seems to me all us make choices - one of Yahavahs choice is to allow all people to retain being alive in a state good enough to get by living out life within the heavenly realm, which is typically, looked at as heresy. Or untrue, or "They die because of second death." And never moved on to Revelation 21, 22. That second death could be the dying of the self of coming to the truth of the Lord Yeshua, going through the fire of God, and find the Lamb and his angels within it, and perhaps able to enter into the Kingdom... This is definitely different than universalism because there is only one way to the Father, and to me that is through Jesus Christ for all those who can read, seek, learn, grow, and eventually even after this life if they didn't fully know, will find out then in that afterlife.
