I am not sure eternal life is that pleasant. I think it just a cover for the fear of death that we all experience. I have known Christians who had panic attacks at the thought of eternal life.
My picture of eternal life is what we had in the Garden of Eden before the fall of man, except that we will not have bodies of flesh.
Consider also, that this God character has no reason to hide from people. If what he is selling is so good, why not make it known. Every scammer makes a promise that they want you to accept on faith only, without any evidence. There is no evidence for God, much less for any afterlife, like heaven or hell.
God is not hiding from people. He sent His son with the gospel message of reconciliation between God and man. You are right in saying there is no evidence for God, neither is there proof there is no God. You are free to choose to believe or not to believe. We still have free will.
And, lastly, consider that this God did not mention Hell until the New Testament. Nothing about Hell in the Law of Moses or pretty much the whole of the Old Testament. Maybe there is something about Hell in the book of Daniel, but that’s about it, but the idea is different from Christian Hell.
I think we have misinterpreted the Biblical references to hell. Jesus’ references to hell were basically warnings against throwing away our spiritual selves, treating it like something that has no value - like throwing it in the trash.
God, allegedly, is the smartest, most loving and most psychologically stable being that could exist. Why does he need to resort to some petty reaction to human doubts?
God still gives us the choice to eat from the tree of life or the tree of knowledge. One offers an eternal spiritual life and the other offers a physical life with no spiritual dimension. We get to choose, there is no petty childlike reaction to our choice by God. We who have taken the time to read the Bible know what the terms are.
