Elon Musk on why the absence of aliens would be far more terrifying than finding them "I have yet to see any actual evidence of aliens, and I'm really deep in space. If there's some actual evidence of aliens or an actual UFO, I'll be there in a second. Is it a UFO, is it advanced technology? That would be very interesting, and hopefully they're friendly" "If they managed to get all the way here from another star system, their technology is going to be far in advance. We'll be primitive compared to them" "But I also think, if there aren't aliens, that's actually perhaps even a bigger concern. Because if there actually aren't aliens in our galaxy or anywhere near us, then this consciousness on planet Earth is like a tiny candle in a vast darkness. A fragile candle. And we should just do everything we can to make sure it does not go out"
