You credit some random chances to the existence of the universe, and by extension, life.
If some molecules were able to fuse together under some ideal conditions to create life, why were the same molecules not able to fuse together under the same ideal conditions to create a simpler thing, say an Embrair E190 jet, or a PnP junction, or even a bicycle?
Maybe they did but seeing as planes and bikes couldn’t reproduce to pass along their mode of making them to their progeny, they were probably lost in the volcanoes and floods.
