There are multiple archaeological proof of Norse presence in Canada - L'Anse aux Meadows is the remains of a whole village. Furthermore we also have historical evidence in the form of the Vinland Sagas, which is Icelandic tales about the discovery of 'Vinland' and encounters with the natives. Taken together the evidence is solid. In comparison there are no historical sources that talk about pre-columbian communication between old-world and american civilizations, and no archaeological evidence either. The word "pyramid" is indeed used by later times to describe buildings both in America and in Egypt, but apart from a similar basic shape, they are fundamentally different in architecture and use. The only reason to assume pre-columbian communication is basically that it would be cool if it were true. That is not good enough for historians though.
