You don't have to believe me....but one day you might be forced to.
That's impossible. The god of the Christian Bible is easily ruled out a few ways. For one, it is described in mutually exclusive terms like the famed married bachelor of philosophy.
For another, the evidence that underlies the theory of evolution only permits two possibilities: the "kinds" evolved naturalistically from the last common ancestral population as Darwin suggested, or life was created by a deceptive intelligent designer or designers. There is no place for a god with infinite power and knowledge that wants to be known, loved, obeyed, believed, and worshiped. Such a creature would have accomplished that goal.
The most likely fate for minds after death is their extinction.
But in the unlikely event that we awaken to an afterlife, all that we can know for certain is that no impossible gods will be there. Most likely, there would be no gods at all - just the minds of the deceased awakening to another world as they did once before in this life, and beginning a second journey of discovery.
If there are agents that weren't in the same boat that we were in - some kind of much more powerful being among us - it would likely be a multitude of beings, and there is no reason to believe that they would judge or punish us.
And if we were slated for some kind of sorting out process, no human being has any idea what that would be like, what would be its purpose, or what would be the criteria used, that is, what are they looking for.
So, the plain truth is that there is no chance that one day we will be forced to believe you, but there is a non-zero chance that you will be forced to believe that you have made a mistake. The good news is that you probably won't be penalized for it.
