What would the world be like if the United States had been formed from the first European colonists to come to North America? The laws, constitution, and idea behind the US would be the same it's just that the country would have been formed way earlier. How would the world be different? How would the United States be different? How would the United States have affected the events in the world if it had been formed this early?
We likely would have collapsed into socialism about 100 years earlier.
