If there is any form of an afterlife such as heaven/hell/reincarnation/ascension, guess what?
You won't know about it until you die. Nor can anyone tell you.
And don't cite the so-called "out of body experiences" that some people have when they clinically die and are brought back to life- these are, in my opinion, either hallucinations brought on by the brain shutting down and neurons wildly flowing everywhere, or your brain is showing you what you want to see, what you expect, upon death. These people might have been seeing blurred surgical lights, but they convinced themselves that they were seeing saint Pete standing at the pearly gates.
Also; as far as the Bible presents it, there are three forms of afterlife. The first is eternal life in heaven, given to a chosen few (cited as 144,000 in Revelation; whether this is a symbolic or literal number, it's obviously impossible to tell) The second is eternal life on earth, given to the "meek" and the "great crowd" (which I assume is the greater majority of mankind) The third is nothingness. Utter death, irretrievable destruction. It's what many contemporary churches interpret as "hell", but obviously a place where people are eternally tormented for what they were born with (the concept of Adamic sin) is a bit contradictory to a loving God. It's referenced to as things like Gehenna, in the Hebrew, which was basically a site where garbage was burned. Once it was burned, it was gone; the garbage does not suffer eternally. It's also referenced to as Sheol, which I believe was a gravesite (cba to look these up now) Revelation also mentions a "fiery lake, which means destruction", and it mentions the "dragon" (Satan/Devil/Lucifer) getting thrown in and destroyed. Not tormented, destroyed, gone, poof, vanish, evaporated, sublimated. And if the devil, who obviously deserves to suffer and burn and be tormented more than any other being in existence, particularly any other human being, is spared that fate, why would humans not be? Why would the guy who essentially fucked everything up for us get off with instant death while everyone else suffers for all eternity?
P.S.: For more of you that want to argue "OH WELL WHAT ABOUT THE SOUL CLEARLY BEFORE THE RESURRECTIONS OUR SOUL EXITS AND DOES WHATEVER"; in the Bible, soul is literally used to mean "life" or "being". Note that in Genesis, Adam, the first man, became a living soul; he was not a soul inhabiting a human body, he was just a soul. It refers to the whole being. You might have heard this version of the term used in some old sayings, where "soul" references to a person (e.g. "Those poor souls don't have any soup") Also, Ecclesiastes chapter 9, verse 5, reads "The living at least know they will die, but the dead know nothing", or in some versions, "The living are conscious of the fact they will die, but the dead are conscious of nothing at all."
EDIT: And to those of you wondering why I'm taking a religious approach as opposed to my typical agnostic/atheistic approach: I think it makes a much bigger impact on somebody when you're able to show them, using their own facts, why they're wrong. I'm not saying Christianity in its entirety is bull (I'd technically call myself Christian) but many popular conceptions (or more fittingly, misconceptions) of scripture over the past 2,000 years have led to a lot of "biblical teachings", used by many churches and denominations today, that aren't really that biblical at all.
