All the believers who state that their facts are so are dishonest!

They state categorically that this, that and the other are facts when they're quite clearly NOT a fact.

They'd be honest if they said "I believe......." this, that and the other are a fact.

It's been said before that the inexplicable was always explained away by claiming that their god did/created this, that or everything else and that is definitely a fact.

I suppose that if someone came along and said that they "believe" the Big Bag happened but it was one of many over time and that the Universe as we know it is only a small part of a bigger, much bigger, super-massive never ending Universe and that they believe that Big Bangs happen every so often in different parts of that super-massive Universe, the whole idea would be ridiculed by many but taken on board by others?

Those believers would be challenged to "prove it" when of course, they can't and they might say "I know it's so" just like religious believers claim that they "know". Really, they know nothing more than what they've read or been told.

Let's be honest, we "know" some things to be true, others are likely to be true, yet more are possibly true but many others are only "true" in the eyes and minds of those want to believe them.
