Again sorry not DF related. I promise this will be my last arguement post.
But these are my own biases, I once repeatedly questioned my friend, a mathematician, about how .999r = 1 , eventually he exclaimed, "Maths isn't 'truth'! It's just based on axioms/rules". Let's hope true scientists and mathematicians don't rely on axioms and suchlike.
Maths is an arbitrary system based on a few basic rules an then used to predict an reveal. You can easily have different rules and turn out with a different system like non-euclidean geometry which changes the nature of parallel lines.
The thing about science is that it's all about predicting and explaining what happens in the world and how. Anything which isn't observable isn't considered to be useful to model. And yes as someone pointed out before science isn't "the truth", any good scientist will tell you it's the best approximation we can come up with. If there is inconsistencies between the currently accepted model and what actually happens and change is need and this has been done in almost every major scientific discovery. This science doesn't say a theory is "absolutely right" but if something is more precise and simplistic. For example ancient astrologers had worked out a system where the sun does revolve around the earth and they could predicate celestial movements fairly accurately but the system was so convoluted and had slight inconsistencies that a model of the earth revolving around the sun became accepted as more accurate.
Also about atheism being less rational becuase no one can prove the existence or non-existence of God(s) then surely it is as rational to believe anything else which can't be disproven. I could say that there's a giant invisible hippo under my bed which you can't interact with in anyway, you'd call me illogical for believing in it but I can use the same arguement that you can't disprove it therefore you can't pass any judgment. No-one's disproved the existence of fairies either.
