Sea Breeze said ".... a man who walked out of a tomb as he claimed he would ...." (in reference to Jesus), but there is no report in the Bible at all of a human (or even angel) seeing Jesus walk out of his tomb! There is thus no report in the Bible at all of anyone witnessing the resurrection of Jesus (though there is a report which makes the claim of people seeing Lazarus walk of his tomb). If anyone can prove otherwise please state the verse or verses.
Furthermore, in a number of reports in the Gospel books of Bible of people allegedly seeing Jesus after his alleged resurrection, some of them say some of the disciples supposedly seeing such did not believe (presumably didn't believe that they actually saw Jesus alive after his death). Some of the reports in the Bible also say that the disciples did not recognize him at first despite having a personal two way conversation with him. The long addition to the Gospel of Mark (which I think Sea Breeze believes is authentic scripture) says that Jesus appeared in a different form after his supposed resurrection. These accounts thus leave room for the possibility that in the accounts of a purported post-resurrection Jesus, the live man allegedly seen by the disciples was not actually Jesus, but rather a a man whom the disciples mistook for Jesus.
[In contrast the Gnostic Gospel of Peter (see https://en.wikipedia.org/wiki/Gospel_of_Peter ) has an account alleging that Jesus was seen walking out of the tomb, and that his cross was seen both following (walking?) out of the tomb and talking! I don't think Sea Breeze believes in that account as being accurate, but if he does believe that Gnostic account then I invite him to tell us such.]
Another possible interpretation of people thinking they saw the Jesus alive after his death, is that they merely had hallucinatory visions of seeing him as such. In the case of the Apostle Paul, he even claims to have seen a vision of the resurrected Jesus Christ, though according to what he wrote he didn't think the vision was a hallucination.
Regarding
Bible verses about the dead being conscious or unconscious, don't
forget Ecclesiastes 9:5-6 (NKJV) which says the following.
"5 For the living know that they will die;
But the dead know nothing,
And they have no more reward,
For the memory of them is forgotten.
6 Also their love, their hatred, and their envy have now perished;
Nevermore will they have a share
In anything done under the sun."
Ecclesiastes 9:10 (NKJV) says the following. "Whatever your hand finds to do, do it with your might; for there is no work or device or knowledge or wisdom in the grave where you are going." That verse (with the word "grave" used in the NKJV translation instead of "sheol") is also completely true and 100% in harmony with atheistic scientific naturalism.
