Yes, but we have insufficient evidence to believe that such a god exists. If our analysis of the myth is that this could have happened by magic, then there is nothing to discuss. Since we don't see magic in the universe, we shouldn't entertain such a suggestion seriously.
I understand your point about "insufficient evidence," but I would go even further to assert that there is no evidence at all. However, framing the debate as one of insufficient evidence misses how people of faith and superstition typically operate. A superstitious person would argue that all of existence itself serves as proof of God’s presence. They often claim faith precisely because they perceive a lack of empirical evidence.
I've encountered many rational thinkers with a scientific mindset who question the relevance of discussing God when evidence is absent. This is a valid perspective. Yet, it’s important to recognize that people of faith often believe that having God in their lives brings them greater meaning and fulfillment.
Reflecting on my experiences, I've observed that some atheists I know struggle with suicidal thoughts and self-destructive behaviors, which suggests there may be some truth to the notion that faith can provide a sense of purpose. If we were to assume the universe is entirely devoid of meaning—an indifferent expanse governed solely by the laws of physics, where no arrangement of matter or energy holds more significance than another—this perspective can be profoundly bleak.
Consider Friedrich Nietzsche: at age 44, he experienced a collapse that led to a complete loss of mental faculties, paralysis, and likely vascular dementia, ultimately requiring his mother's care until his death. This stark reality exemplifies the dark side of a nihilistic worldview.
While some may argue that belief in God lacks scientific basis, it's worth noting that individuals who frequently experience profound moments of joy, fulfillment, or transcendence—often referred to as "peak experiences"—may enjoy better overall health and well-being.
You might identify as a nihilist and view belief in the divine as delusional, but I would contend that I am perhaps a bigger nihilist than you. Nietzsche's fundamental error was not just recognizing that everything is meaningless, but that the very acknowledgment of meaninglessness itself is also meaningless. In that light, it really doesn’t matter how one chooses to interpret existence.
So, I choose to believe in the divine, not only to irritate atheists but also to show that I can embrace nihilism to a greater extent than they can. I go so far down this path of meaninglessness that I include the idea that it doesn't matter whether I entertain delusions about God and the divine.
Ultimately, I’ve never had any of my peak experiences come from religion anyway, so I think the specific delusions a person holds dear may not matter too much in the grand scheme of things.
