What is the difference between the two forms and how do these sentences differ in what they convey?
Yo estuve ahí
Yo estaba ahí
In the present tense, we would invariably use estar when talking about locations or any temporary/continuous state (yo estoy aquí). So, to me the imperfect (the second sentence with estaba) seems the most appropriate past tense in this context. If that’s true, could you please provide some examples where one would use estar in the preterit tense (estuve)?
