Philosophers, scientists, and theologians have explored these concepts, leading to various interpretations and theories. Existence can be examined through different lenses, such as philosophy, science, and spirituality. Each perspective offers insights into the origins of the universe, the nature of living beings, and the potential for life beyond Earth.
