yet you claim being unable to prove either existence or non-existence of gods as both a valid argument against atheism and pro-Gods.
It is valid argument.
You cannot prove God doesn't exist, thus there is possibility that God exists. If you want to believe in God based on miracle(or something you perceive as one) or whatever or just pure faith, you are free to do so.
Scientific skepticism creates us basis for science, where you can not accept unprovable as facts, because the facts can be wrong it would make the false information(being unable to be proven wrong and all), stick in the science, which would make it umm... a bit less scientific. Scientific skepticism doesn't make science always true, but having fallibility as requirement for scientific theory makes science evolving and objective, and being objective and empirical, something that should be taught in schools(if it moves like a photon, looks like a photon and acts like a photon, it really doesn't matter if it isn't a photon).
You don't need to have objective reasonings to believe or disbelief in supernatural, but you do need them to state something as absolute truth to other people. People are allowed to believe in invisible pink unicorns, just like they are allowed to believe that God does or doesn't exist, but I do get a bit pissed when they start stating God or no God, or even worse, creationism, as absolute truth.
That said, I do not believe in God or anything else supernatural for that matter. It just makes no sense to me, having materialistic, deterministic, reductionistic world view. I don't think God is much more likely to exist than the said pink unicorns, but also, I see no rational reason anyone would believe in pink unicorns. Belief in God, while I see it as irrational in itself, actually provides a lot of things some people need. Safety, belonging, esteem... The main thing I critizise religion on is that it upholds some rather irrational conservative views in society, which I think is not exactly great thing at maximizing personal liberty.
I also *know* omnipotent God cannot exist, cause it wouldn't be logical. But if we are allowed to break laws of logics, me saying " I also *know* omnipotent God cannot exist, cause it wouldn't be logical." actually means "I believe omnipotent God doesn't exist"(not really logical but apparently it doesn't have to be).
Well, you're saying we shouldn't attack people's beliefs. What are you doing right now? Are you not attacking the beliefs of every atheist? Why is it ok when you do it? And why is being an Atheist any more offensive than being a Theist?
You are assuming, with absolute truth, that LegoLord is wrong, while you cannot provide arguments for it, as you cannot disprove supernatural. It's not within the field of science. There are no laws of physics that make the "law of God" to appear, so you cannot disprove it exists. LegoLord is only stating what he beliefs in, not absolutes, so it's not attacking anyone's beliefs, while you are stating with absolute certainity that you are right, he is wrong, while having no way of knowing or proving it.
