Religion is one way to do so. There are many other ways as well through identity in a Nation or a Group.
Transcendent ideas and identity keep humans mentally afloat while alive but the reality is we all sink into physiological oblivion. Our ability to be smug about the Universe has a purpose to keep a person mentally stable.
In the overwhelming ocean of life we grab on to transcendent ideas to keep afloat and with faith we walk on water. Nature catches up though and despite our bravado of human language the decomposition of the body rolls on. The bacteria and viruses that ravage our bodies, the various diseases and decomposition that tear at our strength, the accidents, storms, tornadoes, tsunami’s and other acts of Nature that crush us have not been given the memo apparently of the sanctity and dignity of human beings.
Humans need to anchor themselves in some transcendence. The reach for Heaven, Utopia, Singularity. To be significant and to survive.
We demand answers now when in reality we have to wait in uncertainty. We demand a final solution to problems that are beyond our ability to solve. Has modern man taken its faith in the gods and now put its faith in technology?
The Apostle Paul asked who will deliver him from this body of death and his answer was faith in the man god Jesus. Today humans still ask who will deliver us from this body of death but now the faith is in transhumanism and technology to take away the corruption of the body. To deliver one from Nature's wrath of entropy and death.
The feeling that humans need redemption and salvation runs deep. Redemption from a lost paradise and salvation from Nature's wrath and the endless cycle of suffering and mortality. For the Buddha, Nirvana was not coming back to this cycle.
That is the magic of faith it takes away the burden and limits of human knowledge and the body. It takes away the question mark. It takes away mortality. Are bad answers better than no answers? In our reach for transcendence is it hubris based on conceit or desperation? Or the Transhumanist would see it as progress?
