Some of us believe that if you don’t believe in Heaven, God will not accept your soul when your carnal body dies. This could be true; maybe your soul just reincarnates when your body dies if you don’t believe in Heaven, or maybe your soul is discarded and atheism functions as a device of population control. Either consequence could be true––however but for one reason: NDEs sometimes happen to atheists. I think this proves you don’t need to believe in Heaven to go to Heaven when you die, because were that so, atheists would never get NDEs. Pretty much case closed. Atheism will not preclude you from access to Heaven when you die. God does not disown disbelievers.
