This is always my reaction to this theory as well. If someone asks “How did life on Earth start?”, surely we can assume they actually mean “How did life start?”
It’s like if a kid saw a baby, and asks their parents “Where do babies come from?”, and their reply is “Oh that baby lives next door, it came from that house”.
It’s not necessarily the most annoying- but to give an impression that you are people you do not want to live next to, just crank some psytrance. I love me a good doof party, but holy shit I would not want to live next to one.
