I wouldn’t call it “freaking out” - COVID can and does have serious effects on people’s health and nobody can know how sick they’d get if they got it (I must say, I do often wonder how people who think those of us trying to stay safe are overreacting, would have acted during the days of the Black Plague!).
If aliens landed, it would really depend on what they wanted/did etc. Even if they did mean us all harm I can still see some humans forming groups siding with them!!
I’m curious about the size of the universe, I’ll admit - and even though I’m a staunch atheist, I’d love to confirm the whole gods thing and put the issue to bed once and for all.
