Why are other civilizations ignored in the Bible?

[Esquilax]

The story goes God heard their cry when they were being oppressed as slaves in Egypt and decided to free them from bondage, form a covenant with them and give them their promised land in Israel. God likes to get his message across from the poor and humble portion of humanity much like how Jesus was a low status carpenter from Galilee.

Poor and humble people are everywhere, just saying. God could have had a Jesus in every country, and cut out all this confusion and the deaths he knew would result from ideological conflicts over this right then and there. He just didn't.

I'm sure God spoke to people from other cultures as well and this had some influence in the formation of other world faiths.

So why no Chinese Jesus?

50% of the entire world now follow the God of Abraham so it turns out it was an efficient way of doing it.

Yuuup, and according to your doctrine most of them are going to hell for not believing in Jesus, and the rest might be going to hell for various things they don't consider sins but your denomination does. Don't try this generic god equivocation, it's intensely dishonest.
