Since when was America discovered by Erik the Red? He didn't even discover Greenland - he just led the first successful settlement of it.

If we're taking Greenland as part of the American continental landmass then Gunnbjorn Ulfsson is the real discoverer some point in the early 10th century.

For an actual landing on mainland America then we have to wait for Leif Ericsson's landing in Labrador around 1000.
