Imagine if an alien lifeform had terraformed earth this way. We would not have existed.

(There is a hypothesis that life may have been introduced this way to earth, known as the Panspermia Hypothesis https://en.wikipedia.org/wiki/Panspermia)

There are so many chance events that could have gone differently and we would not have existed.

If not for an asteroid, the earth might still be populated with dinosaurs. Would they have evolved to our degree of intelligence and civilization? Who knows?

    The universe may
    be as great as they say,
    but it wouldn’t be missed
    if it didn’t exist.”
