Right, and what are the chances that a life-bearing chunk of a planet from a remote star system happens to crash into earth almost immediately after it's been formed? Seems like a (literal) long-shot to say the least!

Pretty interesting kind of life too - able to survive in outer space for inter-stellar travel durations, able to withstand the scorching heat of ripping through earths atmosphere, then able to escape from a chunk of rock to populate the planet. That's more than pan-sperm, that's super-sperm!

I can't wait for AGI, I might finally have someone intelligent to talk to.
