Exactly. These unfounded absolutes are a sloppy habit, though many of us probably do them from time to time.

Strangely, yesterday I was angrily downvoted for pointing out the same problem with a historical statement ("the world's first paint").

it's not unfounded. there's direct supporting evidence. and they're not really absolute. it's blatantly obvious that the "that we know about" is implicit.
