The Land bridge theory assumes that there were land bridges connecting SEA countries by land in ancient times due to receded sea levels.

It's possible that our ancestors were from the same origin, migrated to each countries and their language developed separately but still had similarities.

It's also possible that there was just a cultural exchange during the era of sea trade.

I'm just pulling this out of my ass from what I remember in history class.
