Fisherman, I do not believe there is an afterlife. I very strongly believe that this life is all there is. I disbelieve the Bible's claims that someone supernatural exists, that something supernatural exists, that something supernatural happened, that supernatural events happen, and that supernatural events will happen. I think that in some cases (probably even in many cases) that the Bible writers were sincere in teaching a resurrection and the existence of the supernatural, but that they were in error in having those views. A number of times even when I was an active JW I had doubts that there would be a resurrection to life. A number of times even when I was an active JW I doubted that eternal life for humans (whether in heaven or on Earth) will ever be real.
Biahi I have seen copies of the book called Heaven Is for Real by pastor Todd Burpo and by Lynn Vincent, but I don't believe the book's claims that the boy actually went to heaven (though I believe that the authors might be sincere in the making the claims). An article at Psychology Today , by a professor of psychology, presents a skeptical analysis of the book. The article says in part the following.
"... Colton never died; according to the movie, his heart never stopped beating and his brain never stopped functioning. Since according to the modern Christian understanding, one’s soul doesn’t leave one’s body until one dies, the idea that Colton’s soul went to a Christian heaven is inconsistent with a modern Christian understanding of persons and death—a view it seems the Burpos endorse."
The writer of the article even states what the view of the authors of the OT regarding Sheol and regarding Paul's view of resurrection, and that such conflicts with the idea of a conscious human soul leaving the fleshly body. In part the professor says the following in the article about the views of the OT authors and of Paul.
"Those authors did not have the dualist understanding of persons that modern Christians like the Burpos endorse; those authors did not conceive of a person as a body and a soul, and they certainly didn't think that your soul separates from your body upon death to enter heaven. For example, the Old Testament authors had a monistic view of a person—a person is made of a single substance—and thought people (bad or good) went to Sheol when they die—a place beneath the ground where the dead simply sleep. (One does not experience Sheol.) For a special person like Elijah to not suffer such a fate and instead enter heaven, one's body must be physically taken there. The apostle Paul, as a Jew, would have been working with a similar understanding and in fact endorses such an understanding in his writings."
In the article the professor also says the following. "If you have to make excuses that are immune to evidence to save your theory from the evidence, that's likely because your theory is false. When making a claim about what has occurred in the world, the first thing a rational hypothesis needs to be is testable. But ad hoc excuses make hypotheses un-testable."
