We don’t even know that it occurred on earth at all. It might have occurred elsewhere in our galaxy and traveled to earth via asteroids.
That would make it more likely that there’s life on other planets, not less likely.
Most planets and stars in the universe are not in our galaxy. If our galaxy has a bit of unicellular life because some very rare event happened and is the only galaxy with life, that fits to a universe where we are the only intelligent species.
