I can provide you with information about how atheists generally approach questions about the origin and existence of the universe.
Atheism is simply the lack of belief in a god or gods. It does not provide a specific framework or set of beliefs about the origin and existence of the universe. Consequently, atheists may have different perspectives on this topic, as they can hold a variety of philosophical, scientific, or metaphysical viewpoints.
Many atheists rely on scientific explanations and methods to understand the universe's origin and existence. They often defer to the consensus of the scientific community, which currently supports the Big Bang theory as the most widely accepted explanation for the universe's origin. According to this theory, the universe began with a singularity and has been expanding ever since.
When it comes to the question of why the universe exists or how it came into being, atheists may look to naturalistic explanations and scientific theories rather than invoking supernatural or religious concepts. They might explore concepts such as cosmology, quantum physics, or other scientific disciplines to better understand the nature of the universe.
It's important to note that not all atheists are scientists or have in-depth knowledge of scientific theories. Like anyone else, they may have varying levels of interest and expertise in cosmology or physics. Atheism itself is solely a position on the belief in gods and does not dictate any specific views on cosmology or the origin of the universe.
It's also worth mentioning that atheism is not a unified or organized belief system, and atheists can have different viewpoints on a wide range of topics, including the origin and existence of the universe. Therefore, it's always best to engage in open and respectful conversations with individuals to understand their specific perspectives.
