In a video with nearly 16,000 likes, one TikTok user is claiming their ancestor was like “Captain America” after finding a photo that seems to show the young soldier holding a bucket and an object with a striking similarity to an iPhone.

Jimmy is one of many TikTok users that claim to witness time travellers – or even predict the future themselves. In October, one TikTok account predicted a giant asteroid would destroy half of America, and new life would be found on distant planets.
