Anecdotal Evidence

[brewer]

Suppose I tell you, 'I was taken aboard a starship from the Gilflingian Empire.  They explained to me their benevolent purposes, took readings of my brainwaves and brought me home.'  This is an anecdote.

Suppose I tell you, 'I was taken aboard a starship from the Gilflingian Empire.  They said people wouldn't believe this story, so they sent me back with detailed instruction on how to build a cold-fusion generator for $12, how to cure all cancers, a sure-fire way to settle the troubles in Gaza and Syria, and how to safely and rapidly increase Earth's agricultural production 15 fold.  See?  The instructions are engraved right here on these plates of trivactium, a non-conductive metal alloy made of stable astatine.'  This is evidence.

And never the twain shall meet.

Not until you build the generator, settle the troubles and increase the production. Until then they are just words on something strange.
