Which two civilizations had such a great influence on later cultures they were called the "mother cultures"?

I believe the answer is: The Olmec and the Zapotec

Both of these civilizations left a considerable amount of artefacts which believed to be much more advanced compared to other civilizations in term of its arts and culture (such as statues, masks, and paintings). Because of this, many historians believed that the development of arts and culture on the rest of the world were influenced by the culture of olmec and zapotec

well this is going to be a long answer lol ok so the visigoths were a branch of the goths who frequently raided rome, uh the hunas attacked the guptas a lot and weakened them, uuhm of course the romans used math and science in there every day lives i mean they had a whole empire to run, and rome was split into east and west by a general named diocletian. hope this you! : )
