I was wondering, and I know this probably sounds ASB as hell but I can't get over the idea of Bronze Age trade routes stretching basically around the world, with the Americas being connected to early trade routes.
Is there any way to basically make this possible? It seems to wildly impossible because irl major and sustained contact happened in the 16th century, but there ought to be some PoD that could make trade routes up into Europe and across the Atlantic, or up from Japan to Alaska and down, no?
