Question from Jon:
At most, we all choose what is rational in believing or being convinced about something. While searching for answers, I have stumbled upon studying atheism as a choice for my belief but a find it highly irrational. Firstly, atheism appeals that believe in a god/cause/deity is highly irrational because there is no objective evidence to back-it up. But when I analyze it in terms of pure rationality (because the counter option can’t also be validated), I stumble upon choosing between
A) the universe is just a brute fact, nothing caused it to exist, its here because it is here
B) the universe is caused into existence by an agent/cause/god (in my case I don’t define the cause)
And option A which is (correct me if I’m wrong) the heart of Atheism is highly irrational, because so far, inferred from the existence of humanity, humans discovered things or events to be caused by “something” and yet option A completely contradicts it. I believe science breaks apart when something is just assumed as a brute fact. If I have inconsistencies in my analysis, please enlighten me. How does atheism become rational with these arguments taken into hand?
Answer by SmartLX:
Atheism takes no position on the universe’s origin or lack thereof, except to say that it’s unlikely at best that a god was responsible because belief in a god’s mere existence (let alone agency) isn’t justified. Option B is fine for a lot of atheists because if there was a cause, it doesn’t have to have been anything like a god. It could be the quantum foam, or another universe in an infinite series, or any number of phenomena we haven’t even thought of.
That said, option A is counter-intuitive but it’s not as absurd as it sounds. If the universe is as eternal as many gods are supposed to be, then it doesn’t need a beginning, and it’s simpler to just suppose that the universe has this quality than to inject a hypothetical separate entity. More significantly, though, everything we’ve ever seen come into existence is made of existing material. Human beings are made of elements found all around us on this planet, and fueled by energy largely traceable back to the Sun. Thoughts and ideas come together in networks of neurons in our heads, powered by electrical energy. Most every building is made from things harvested from, or grown in, the earth. If, by contrast, the universe came to existence out of what could be defined as nothing, it wasn’t like anything we’ve ever seen occur and therefore we have no authority to declare that there must have been a cause. Following on from that, there’s no reason to suppose the existence of a god just for the lack of alternative explanations, and if as you say there’s no objective evidence for gods then there’s no reason to believe in them at all. Thus atheism has a rational basis at least to some extent.
