emphasizing someone has definitely done something like "I did go there" [closed]

The verb "to be" is unique in that it doesn't need "do" to do anything in simple tenses! Not to negate, not to form a question...it's a free agent!

To emphasize just use intonation/pitch: But Honey, we WERE there!

For most verbs, do (and other parts does, did, done) are required in questions and negatives, but with an affirmative statement are optional, and normally used only for emphasis or contrast. They are always followed by the simple form ("infinitive") of the verb.

However, in most varieties of English, this construction is not available with "be": it is simply not grammatical to say "We did be there". As Jim says, if you need to emphasise, you have to do it in a different way.

There are some dialects of English which do allow "do" with "be"
