Where is your proof that two fingerprints can be the same?
And before it comes about, the absence of proof isn’t proof. “Could ofs” and “maybe exists” don’t really cut it. I hope you understand this is why appeals to ignorance don’t work and you can’t use the fact that we haven’t gathered all data especially when all the current data point squarely point one way.
This is why labeling something as false, a myth or a fantasy needs more than just a slight possibility.
We could label physics as a myth by arguing we just haven’t found the cases in which it doesn’t work yet. These things have happened before and there’s always a slight possibility but to bungle about saying it’s a myth is a bit silly imo.
