Titanic

If the government has confirmed UFOs/UAPs are real, why haven’t we ever seen them actually save people? Like the Titanic, plane crashes, natural disasters, etc. If something out there is advanced enough to travel here and observe us, wouldn’t you think at some point there’d be evidence of them interfering when humans are about to die? I’m not saying this proves aliens aren’t real. Maybe they don’t care, maybe they have some kind of rule against interfering, or maybe we’re assuming these thing...
