Your Team, knows it was a false bug?
Welcome to the Atlassian Community!
No, that would lose you the tracking information that you're relying on to inform your sprint metrics and progress.
Mark it as "done", ideally using a resolution that says something like "cannot reproduce", so you can report on evaporating bugs in the future, and take the credit for fixing it (by finding that it doesn't happen any more)
Definitely agree here - resolving with a "Cannot reproduce" resolution/comment/tag or something will help with your reporting/metrics down the track. If you're tracking time in Jira as well, you don't want to lose the fact you may have spent an hour trying to reproduce a bug cause you deleted the ticket.
