You miss my point, or prefer to pretend you don’t understand it. There is no evidence of heaven. It apparently exists in the minds of the hopeful, but there is no evidence of that is really exists, and no reason to believe it exists. It is therefore safe to say it does not exist, but if you have proof otherwise, I would love to see it.
I hope that helps. I can only explain it to you. I cannot make you understand it.
Do you pray?
Anyone may reject the testimony he deems suspect, but only a myopic, closed-minded person rejects the existence of what he has not seen nor experienced personally. Such a person would be barred from sitting on any jury in any courtroom anywhere in the world.
You reject the notion of heaven based on a lack of evidence...but in order to be persuaded of its existence, you require not just evidence, but proof.
Paul, John, Peter, James, Luke and Matthew's testimonies regarding heaven are obviously not enough to convince you of its existence, just as the testimony of millions of Christians regarding their personal experiences with God are not enough to persuade you of His existence. You reject their testimonies...and because they have only testimonies and no concrete proof, and you require proof in the matter, you simple-mindedly reject the evidence contained in their testimonies.
A slightly wiser man would adopt a wait-and-see attitude in the matter instead of rejecting it outright.
