Thank you! I appreciate the alternative perspective and the flipped argument you presented. However, I'd like to address a few aspects of your argument and offer some clarifications.
This is largely echoing what Tom said, but I think it's important to note that the burden of proof typically lies with the one making a positive claim, in this case, the theist. It does seem true that neither theism nor atheism (as we know them) has sufficient evidence to warrant an end to the discussion. However, atheism is often seen as a rejection of the positive claim (i.e., the existence of a deity) due to insufficient evidence rather than making a claim in itself. In this sense, atheism does not necessarily rely on faith and personal beliefs, but rather a healthy dose of skepticism and a demand for evidence.
Regarding Pascal's Wager, it is indeed an interesting thought experiment, but I don't think it's without its flaws. In this case, it assumes a binary choice between belief and disbelief in a specific deity. This seems to neglect the multitude of religions and dieties that've surfaced through history. It seems that choosing to believe in one deity could lead to "infinite loss" if the true deity turns out to be another, for example.
As for the Cosmological and Teleological arguments, they do offer interesting perspectives on the origin of the universe and the apparent order within it. However, these arguments are not without their criticisms, either. For instance, the Cosmological Argument relies on the assumption that everything must have a cause, which we don't necessarily know to be true at the quantum level. It sounds crazy, but much of what was previously unknown to science sounded crazy as well.
Take, for example, ancient cultures and religious texts that said things to the effect:
"How can water fall from above? Ah, it must be an ocean above us held back by a dome. That's how we get rain."
While it's true that there are many aspects of reality that we are yet to fully understand, invoking a deity to explain these unknowns seems wrong (the "God of the gaps" fallacy). Historically, gaps in human knowledge have often been filled with supernatural explanations, only to be replaced by natural explanations as our understanding advances. I will accept that the existence of a deity might be possible. But relying on it as an explanation for the unknown might hinder our pursuit of knowledge and understanding.
Even if we assume everything must have a cause through our current understanding of nature (and ignore emerging quantum theories), it still seems like quite the stretch to posit a particular deity or religion. The Cosmological argument seems to advocate that the diety is exempt from laws of causation because it's necessary, but I don't see how the same couldn't be said about the cosmos itself. Additionally, the Teleological Argument has been challenged by the theory of evolution, which provides a natural explanation for the complexity and order we observe in living organisms.
These replies are grossly short considering the expanse of the topics, but hopefully it helps to continue the conversation
