How did having a surplus of food cause a civilization to develop?

answer: "as an obese disordered country that has great food and fun places but has a bad government"

explanation: my friend in britain told me this

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! : )
