Google search Sanskrit Numbers to see the similarity of those to the English words for those numbers, not exactly the same but close enough (with twists such as the Sanskrit word eka for one like once, and the Sanskrit word panca for five like pent as in pentathlon, and the Sanskrit word for four catur as in the English word quarter) to see that those people groups had spread to the East and to the West after the Tower of Babel, the languages from the same source, progeny of Japheth, the Indo Europeans.
