It's not uncommon for people, including atheists, to experience moments of awe, wonder, or gratitude for the world around them, even if they don't believe in a traditional concept of God. These feelings can be attributed to a sense of connection to nature, humanity, or the universe, and can be deeply meaningful to individuals regardless of their religious or non-religious beliefs.
Atheism, in its most basic definition, is the lack of belief in a god or gods. It doesn't dictate how one should feel or perceive the world. Atheists can find beauty, meaning, and gratitude in various aspects of life, such as relationships, acts of kindness, scientific discoveries, the wonders of nature, and human achievements. They may attribute these experiences to natural processes, human ingenuity, or the interconnectedness of living beings, rather than a divine being.
Ultimately, the experience of gratitude or appreciation for the world can be a deeply personal and subjective aspect of human experience, and it is not limited to any particular belief system. Different people, regardless of their religious or non-religious affiliations, can find solace, happiness, and wonder in their own ways.
