Lief Ericson beat them both to North America!!!!!
I think so too, at least as far as North America is concerned.
Vikings were fishing off the coast of Newfie land long before the Portuguese and Spanish. There are old viking burial sites all along the Nelson river, so they were well into the Hudsons bay exploring, not just off the coast, fishing. They were bored of fishing by that time, and set off exploring :o)
