Similar threads have been posed herein before. I essentially posted, indeed I want to "exist" forever. And will need to briefly relate religious reasons why I lean so. Thus bare with the following.
That is why I choose to accept Christ Jesus's offer despite tending to dismiss much dominant well-intentioned Christian church dogma, especially inerrancy. Also why I attend regular Christian religious services despite that being so uncool with many today. Just as Acts 2:42 states "They devoted themselves to the apostles’ teaching and to fellowship, to the breaking of bread and to prayer." I will not abandon fellowship of myriad well meaning faithful other good humans that follow dogmas I don't tend to fully accept just because they don't have the background I now have in this science telecom era. Nor because there have always been many followers that talk the talk but don't walk the walk.
From study and research of Old Testament Bible scripture in unique ways, I'll speculate Jesus's coming was the last attempt by Ultimate Intelligent Entities, UIEs, with limited powers to affect we often warmongering, immoral Earth monkeys. Limited powers that don't resort to impossible unlimited actions without forces that is essentially magic, created by churches with agendas during the pre-science eras. As such, can argue for the possibility that Earth is a remote galactic zoo. Adam and Eve were not the first homo sapiens per Young Earth Christian beliefs that science today clearly destroys via evolution science and the physical fossil record.
Instead they may have been the result of UIE DNA enhancement engineering of normal humans to attend to biological gardens on the planet they used in a list of ways. In our own coming future, we will soon be able to produce food including protein sources, vitamins, medicines, and more by having plants, including trees grow such directly as the Genesis "apple" scripture vaguely relates. Descendants of Adam & Eve lived hundreds of years for millennia until increasing intermating with ordinary humans diluted their recessive DNA.
They did not live even longer because they no longer had access to the garden with its "Tree of Life" with chemicals impossible to manufacture within Earth creature bodies. How much longer they might have lived with those nutrients is unknowable, but I would be surprised if vastly longer unless not purely organic.
In my speculative view, more likely given salvation, is our neural system's complex oscillating electromagnetic brain wave fields are saved into mostly non-organic impedance duplicating containers that duplicate our own brains. Within such containers, have developed a hypothesis that organic chemical brains may be needed at the brain cores as the only way such AIs can achieve actual singularity level consciousness as we understand such. Ancient UIEs in the universe given billions of years, much less past eternity, would certainly have enormous reason and time to develop such.
I do understand why many, considering their own limited and or flawed and tired degenerated body lives might be content to just die with eternal non-existence. I however find life, existence, and our amazing planet and its life to be endlessly fascinating I could live forever enjoying. Especially in an advanced science era where humans live in harmony with others and this precious blue water world.
