As one atheist, I'll enlighten you. I would love an afterlife to exist, preferably something nice. Who the hell wants a meaningless life in the absolute sense or a mortal life, pffff? What probably happens is nothing, a bit like when you smash your mobile-phone against some rocks and you have a particularly strong arm. As an atheist, or person, I'm not interested in fantasies if they're not true. Don't get me wrong, I love fantasy and sci-fi but that's a different context. It's entertaining
I think you will get your wish for an afterlife. I also think the orthodox churches have got things screwed up beyond repair when it comes to the subject.
Just for your entertainment, I'll tell you what I understand the scriptures to say. I'm in no way asking you to believe it. I just think it may be a different twist on what you've heard from the aforementioned "fubar" church doctrine.
1) When we die on this earth we die. There's no floating up to heaven or going down to hell.
Ecclesiastes 9:10,
Whatsoever thy hand findeth to do, do [it] with thy might; for [there is] no work, nor device, nor knowledge, nor wisdom, in the grave, whither thou goest.
In simple terms, dead people are dead. That right there is believed by few, including 99% of Christians. I don't think I'm "interpreting" anything here. It's pretty simple grammar, without any big words.
2) For those who believe in Christ, he will return and gather them together with him.
1Thess 4:17,
Then we which are alive [and] remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.
The "we" (the second word) is, from the preceding context, folks who accepted Christ as their Lord. Once again, no complicated sentence structure. Just says what it means and means what it says. No interpretation necessary.
Even before they die, Christians have already been judged and found OK.
Rom 3:22,
Even the righteousness of God [which is] by faith of Jesus Christ unto all and upon all them that believe: for there is no difference:
Most Christians, I suppose in an attempt to show humility, go bananas when I tell them they are as righteous as God, but I don't know how else to read this verse. In any case those who accept Christ are guaranteed a seat in paradise, not because of their work, but because of Christ's work.
3) As to those who didn't accept Christ, all is not lost. I'll stop quoting verses for the sake of brevity (I'll be glad to give them to you later if you wish), but suffice it to say that after Christ gathers the together the Christians, there will be two resurrections of the non-Christians. During those judgments God will grant eternal life in paradise to those who, although they didn't accept Christ, nonetheless lived decent lives. I strongly suspect that will be the case for the vast majority of people. The scriptures say many times that He will judge people by their hearts. People, especially Christians unfortunately, judge by appearance. They seem to want to take God's job over, but that's another story. The really nasty people (again can't see who by appearances, not our job) will quietly go back to the grave where they will no longer exist. They will be back to the state of no consciousness mentioned above in Ecclesiastes.
4) Scripturally, the lake of fire is for devil spirits, not for people.
That's probably more than you wanted to know, but there it is. I trust it is at least a different take on what you may have been taught, directly or indirectly, by the churches.
Take care...
