never know unless you look. There are 2 potential candidates right here in our solar system, maybe 3 that are much easier to look at than something light years away.
I know some folks don’t believe life is out their because of religious beliefs. For a universe that is infinite, why would God make it so empty and devoid of any other life?
Scientists have not determined whether the universe is infinite (that is, there are an infinite number of galaxies, stars, and planets).
What God was thinking when He made the universe would only be known through direct divine revelation, and His divine revelation does not address whether or not God created life (edible or otherwise) on other planets or exoplanets.
From an honest look at the Fermi Paradox it would seem that there are no other extraterrestrial beings in the Milky Way galaxy with the capablity or desire to travel to other planets, including our own
Also, there are an increasingly discovered number of galactic, solar, and planetary parameters which have a limited range of values necessary for the existence of carbon-based sentient life, capable of travel to other planets. Combined, these parameters make the probability of ET a very, very small number, even in our galaxy of billions of stars.
Looking for habitable planets around other (nearby) stars is a good idea, since the human race will need to terraform and populate such planets in the future. But reports hyping the existence of life on exoplanets with only one or two parameter values within its habitable range, are simply ignorant or dishonest.
