This is one more of those things I should have listened to my child self about.
I don't know how I knew it, but I remember thinking when I was a kid about this sun standing still business "well, then science will have a record of that, and if they don't, they will, because that would leave some sort of evidence". And even then, I was expecting it to leave both physical evidence, and historical, multi-cultural evidence.
But somewhere along the way, I just accepted it as "truth" w/o the evidence. I put it out of my mind.
It's fascinating to me to think that even as a child I knew in my gut that real things leave real evidence - that absence of evidence IS evidence of absence.
