Why is human life so short?

According to theology, human life is doomed. According to science, once human cells divide, they will lose some enzyme telomeres. The survival time of a cell is 3 years, and humans can divide up to 60 times. So in theory, the ultimate life span of human beings is 1, 80 years. Because people will engage in various social activities when they are born, eating and drinking water will accelerate metabolism and accelerate cell division. So humans generally don't live to 100. The age of 180 means that when a person is born and can survive without eating, drinking or doing anything, cells can divide 60 times. Scientific research shows that cancer cells that really cause human death actually repair the enzyme telomere damage caused by cell division, which means that the only way to live forever in science is that your body has cancer. But at the same time, you must have an antibody in your body to prevent cancer cells from spreading and invading your body. Your body must always have cancer cells to achieve immortality, but from a scientific point of view, this theory is obviously untenable. First of all, if human beings live forever, they will violate the laws of physics, so the universe is very big, and they must emigrate to other planets to avoid destroying the ecological balance. Secondly, several planets suitable for human habitation have indeed been discovered in the universe. But they were all discovered by the Hubble radio telescope hundreds to thousands of light-years away, which means that human beings must invent superluminal to immigrate conditionally. At the same time, according to Einstein's theory of relativity, if a person sits on superluminal objects, it will trigger the time expansion effect, that is, the future that will be crossed. Similarly, human beings will return to the past when they are absolutely still (it should be noted here that stillness is not static, and our earth is autobiographical and rotates every day). This also violates the laws of physics. Moreover, as long as human beings engage in various social activities, they are bound to experience various potential threats that may lead to death. Unless human beings become invulnerable like the Monkey King, it is impossible to achieve absolute immortality.
