It is conjecture to you. But not the faithful. Sometimes the non faithful are too quick to “correct” them. I’m not sure why they feel compelled to do this. I am a Christian and my faith wavers all of the time. I ask too many questions. But most studies say that Christians on average lead happier and better lives. So over all it’s a good thing. (I’m not searching for a link.)
Or the beginning of a new one. What do plants eat? Where does oil come from? Two questions that have already been answered by science.
The law of conservation of energy is a law of science that states that energy cannot be created or destroyed, but only changed from one form into another or transferred from one object to another.
If we are made of energy and not flesh, we cannot be created or destroyed either. Our bodies can, but we cannot. All religions agree that we are not flesh, blood, and bone, but rather spirit. In other words, energy.
Will we die though? Absolutely some of us will but science is rapidly reaching a point where they will be able to halt and even reverse aging. And they are reaching a point where they’ll be able to 3D print organs built from our own DNA so there is zero chance of rejection. And every day medical science improves in stopping diseases, many of which like cancer are rarer in younger people so as aging is halted you’ll see cancer rates plummet.
Accidents will still happen and maybe a meteor or some or other cataclysmic event comes that wipes out humanity but there are people alive right now who barring one or the other of these things have a chance to live forever.
I’m not happy to know that I will die. And that is one of the foundations of existential psychology. Since I don’t believe in god, I cannot say that my faith consoles me (or guides me, or whatever). I’m just going to die and I hope it is not painful and I hope I’ve taken care of my loved ones. But stuff happens. One of the best books I’ve read on the nature of death . . . the fear of death . . . is by the great psychologist Irvin Yalom. It is in part his own struggle with the fear of death. I highly recommend “Staring at the Sun.”
