Credible evidence is a rare phenomenon vs total amount of information.

Things that can be demonstrated (and re-demonstrated) by math - chemistry and physics - can be credible.

Experiments that can be measured accurately and replicated (and have been).

Things like ice-cores and geological records. Proper fossil records.

DNA. Some forms of forensic analysis (basically physics).

Engineering schematics / plans that can be replicated.

Archeological records of many types.

Bitcoin actually lol

Not much out there that I personally feel is rock solid credible evidence.
