Let me offer a little analogy for the non-believers to ponder....
Imagine a guy we'll call Joe.
Joe was born blind. He has never been able to see.
He has all his other senses and is a fairly intelligent person.
All through his life, people have tried to explain to him, the beauty of a rainbow or sunset...
But since he doesn't know what color is or have any sense of sight or what that even means, he maintains they are pulling his leg.... He says, "You guys and your mythical fantasies! You can't prove ANY of that to me!"
Of course, people try to explain that he just isn't able to see... but he doesn't know what that means.
Is he correct?
The optical system of our eyes is very narrow. We have invented machines to detect & even use the rest of the electromagnetic spectrum. We even impressively invented machines to see the tiny that we cannot see and the far away we also cannot see.
Your analogy is false. If he is intelligent he knows what others see. He does not believe what others imagine.
He doesn't know what "see" means. It's a sense he has never experienced. You can explain it to him all you like, you can tell him that he is wrong and just because he can't see it doesn't mean it's not there... but he knows not what you're talking about.
I used the analogy to illustrate a point. You are incapable of "seeing" what others see. For you, no matter what anyone says or any evidence offered that isn't within your range of physical senses, it simply doesn't matter.
