In a scene, we see Scott's ex-wife (Maggie), her husband (Jim), and Scott's daughter (Cassey) are watching the TV and a report about a giant creature (Goliath/Scott's huge form) in the city is showing; the reporter says It is NOT KNOWN what or who that thing is.
Also, Maggie and Jim look at each other surprisingly like they don't know the identity of Goliath; but Cassey is smiling; thus she knows it is her father.
Well, people knew about the Germany incident; so the reporter makes no sense.
Also, Maggie and Jim don't know it also makes no sense; because sure they know the reason for Scott's house arrest; and well, when people do know, how can Maggie and Jim don't know the events that occurred in Captain America: Civil War and Ant-Man? See 1:33:18 of the film to watch that scene.
