How would the world be if it was the biggest planet and how would life be

if it was the biggest planet it would be have most likely undiscovered land and animals since there is so much to find. life would most likely be good but there will also be more crime since there is more population all throughout the world. maybe less extinction since there will be a widespread of animals. in conclusion these are some of the many things i believe the world would be like if it was bigger and how life would most likely be. :)
