All you can ever do is insinuate that the idea of pre-Viking transatlantic contact is somehow absurd, when of course there's nothing absurd about it. You never dispute the mountain of historical, archeological, anthropological, and genetic evidence proving the presence of Europeans in the Americas before the Vikings, because you can't.
What genetic evidence?
Most of ancient Chachapoya genomes that you tested have very low SNP counts. With such low coverage, their autosomal results are uselesss. The only ones of relatively good quality are NA40 and NA42. I have just uploaded NA40 to GEDmatch and I don't see any European admixture there (this "North-European-Mesolithic" was actually a Mongoloid-admixed population similar to modern Saami people / Lapps, so they just shared some ancient Northern Siberian ancestry with Native Americans):

That guy was one of the Chachapoyas:

You cannot possibly be more purely Amerindian than this ancient Chachapoya guy.
BTW - if you uploaded other Chachapoyas to GEDmatch, give me their kit numbers.
