As far as I know, It is Correct

Hi, We have to use Do for First person(l),second person (you) and all others plurals in the present tense . Does used for he, she, it in present tense. remember ., I do, you do, they do but he does, she does, it does . in the past tense we use Did for all . I did, she did...etc . have used in present perfect. Do- have does - has I have, you have . but she has, it has. had used in past perfect . had-did am always comes along with I . it is similar to is, was (be verb). I am, he is, she was...

Witness - Evidence. ex: this case doesn't have any witnesses. another meaning is Seeing. Today we witnessed the lunar eclipse.
