What do you think is scarier, the idea that we are alone in the universe or the idea that we aren’t? Why?

I'm a bit late to the party but I have a theory about this.

I think humans are just too early in the universe's history. I'm almost certain that we're alone but it's only because we were probably the first to evolve to sentience. On the cosmological scale, the universe is actually pretty young and our time in it will only be a blip in the proverbial line that represents the age of the universe.

Billions of years from now whenever a species discovers scraps of humanity that survived the turmoil of time, I wonder what kind of knowledge they would gain.

I can't wait for our species to be wiped out before there's a new sentient life form. Or maybe humans evolve into different life forms when we travel to and live in distant galaxies for generations. Homosapiens could become the "Neanderthals" of a bunch of other species like 10,000 years from now.
