We don't agree. You're now saying anything is evidence of anything, which just makes the word "evidence" meaningless.

In real life, when people say "A is evidence of B" they mean strong evidence, or even overwhelming evidence. You just backpedalled by redefining evidence to mean anything and nothing, so you can salvage an obviously false claim.

Nobody in the real world says "rain is evidence of aliens" with the implicit assumption that it's just extremely weak evidence. The way English is used by people makes that sentence simply false, as is yours that anything previously not solved is evidence of AGI.
