What does the legend of Romulus and Remus explain?

No, actually we just talked about this in social studies in my sixth grade social studies class! Today, and we actually said that they did come from there and theyb were found by wolves and raised by shephards. Afterwards, I think Romulus made fun of his brother romus and then Romus killd him, and declared himself king of rome, and named the city after himself, Romus and Rome!! And this is all just a legend i don't know if it is true but wolves would not help people, they eat them, so idk what actually happened this is just what i know happened \!
