Atheism is a lack of belief in the existence of deities or gods. It is not a unified belief system with specific doctrines, and atheists may have diverse perspectives on various topics, including evolution.
The theory of evolution, which is widely accepted in the scientific community, explains the diversity of life on Earth, including the development of different species, including humans, over time. Evolution is a process driven by natural selection, genetic mutations, and adaptation to changing environments.
Regarding the absence of wings in humans, atheists who accept the theory of evolution would explain it in the context of natural selection. Evolution doesn't aim for perfection or a predetermined endpoint; rather, it is about the survival and reproduction of organisms in their specific environments.
Humans are a result of a long evolutionary process, and our current form is a product of various adaptations that have allowed our species to thrive and survive in our environment. While birds and dinosaurs evolved wings as adaptations to their specific ecological niches and lifestyles, humans evolved differently with distinct advantages, such as complex cognition, the ability to use tools, and upright walking.
Regarding the concept of God's punishment and original sin, it is essential to recognize that interpretations of religious texts and beliefs about the role of a deity in the natural world vary among different religious traditions. Atheists, by definition, do not accept the existence of gods or divine punishments, and they rely on scientific evidence and rational inquiry to understand the natural world and human existence.
It's important to respect diverse perspectives and engage in thoughtful discussions about these topics, considering scientific evidence and differing worldviews. The relationship between science and religion has been a subject of ongoing debate and discussion for centuries, and people continue to explore and reconcile their beliefs in light of new knowledge and understanding.
