I am an atheist.
But I admit to the possibility of other sentient material life forms who may be able to utilize the Many Worlds Interpretation of Quantum Mechanics and travel to an infinite number of universes just an instant in time away from our universe.
What do big brother sentient beings do? Since cooperation is necessary for a culture to evolve to its highest potential (you either get along or kill each other) these big brothers of the universe jump around making subtle adjustments that help other sentient entities evolve.
The payoff for the big brothers is the marvelous products that can emerge from the interconnecting minds of trillions of beings. Perhaps the ability to create new universes by utilizing energy of galaxy clusters - WHATEVER. Use your imagination.
Perhaps a "personal god" is a placeholder for cooperation. Utilizing the natural desire for survival built into competing species these entities "bribe" us mortals into acutally believing we will live forever as long as we love (cooperate) with one another. Everlasting life is a trick to make us willing to sacrifice for the good of the whole.
That's where I start to worry. None of us are important. We are all expendable because there are an infinite number of experiments going on with an infinite number of Bobs, Teds, Carols and Alices that work as modules. In this SciFi like universe progress is made by jettisoning our selfish desires for status, food, sex, which all are the basis for war but have been essential to climb the ladder of sentience.
You get a group of people and tell them they are special. You eventually send a special envoy who tells them that they aren't special. They kill him. This impresses people. He becomes the model of self-sacrifice. Since no nation is special there is no need to kill others. You let all the "special" people create a terrible world and bring it to the edge of destruction. The people who aren't special actually become unique because they survive the destruction because of their worldwide brotherhood based on self-sacrifice. The world is shaken by the chaos but impressed by the survival of those who cooperate and have self-sacrificing love.
Everyone learns the lesson. At that point the big brothers let them start associating with the more advanced societies of the cosmos.
Back to why I worry. Since everlasting life is just a gimmick I'm not really going to live forever as promised. I will either die for the good of all or just die anyway.
"It may be you will be hid on the day of Jehovah's anger."
But then none of it matters on a personal level because there are an infinite number of each of us moving along some continuum somewhere.
