No that's obfuscatory bollocks.
The point is that nothing is completely certain in this world but some things are so easy to discount that we can talk about them with what amounts to be certainty.
We can demonstrate that the Christian god and Christian ideology are incoherent concepts.
No, Nearly Sane is correct. If, as you seem to suggest, Christianity is one of those "things that is so easy to discount that we can talk about them with what amounts to be certainty", then the religion would not still have the overwhelmingly powerful influence in the world that it has, and we wouldn't have been arguing against it on this board for years. If you are particularly referring to NS's suggestion of a psychopathic deity who created us to cause us pain and can do what the hell he likes, then that suggestion is just as plausible as Christianity, and likewise, unprovable. That such as suggestion is "easy to discount" has to be considered in the context that such a belief was at least half of Gnosticism, which was a powerful rival of Christianity at the beginning, and has had its courageous adherents throughout the centuries. The get-out clause for Gnosticism was that beyond the evil creator god of the material world was the pure and good world of the spirit to which humans could escape eventually. That to me is equally unprovable, but some how makes a bit more sense than Christianity.
I hasten to add, I haven't entertained Gnosticism as a likely possibility for at least thirty years, and have been muddling along with my IGnosticism well enough
