This is an interesting question, but it supposes nations like Asia or Africa wouldn’t venture off to the Americas themselves (in which many native Americans have connections to Africans). If your question about another way to reach India not going west, then they’d go East, by land. I believe it was just to make it faster to travel by sea though and for more resources. Natives and Africans didn’t colonize (from my research) and if they did it wasn’t nearly as impactful or as cruel as Europeans had done.
