The Norse did however inspire Columbus. Nicholas Niger's map of Greenland inspired Columbus to take a trip to Iceland, which he was convinced was an island off the coast of India. That was what ultimately inspired him to cross the Atlantic.The length of the settlement is historically relevant in this case to analyse the consequences. The Norse settlement was historically inconsequent. It didn’t unite the continents as the voyage of Columbus.
Same can be said about the potentially other arrivals of others to America. They could exist, but they didn’t had consequences.
Maybe my bias is working here, but one of the previous arrivals that if existed could had a historical consequence was the Portuguese one. Because if existed it could be on the origin of the change of the meridian of the Tordesilhas Treaty to the West (1494), after the pope’s proposal (1493), as asked by the king D. João II, and allowing Portugal to set a bigger foot on America, and thus allowing the existence of Brazil.

Also, it's not unlikely that North American indigenous traders were regularly docking in Iceland, Ireland and even Scotland, at least after the Vikings arrived.
