Old photo has internet convinced Greta Thunberg is a time traveller

The Internet has a new favorite conspiracy theory, the New York Post reports.

The girl on the left in this 1898 photo unearthed from archives at the University of Washington bears a striking resemblance to climate activist Greta Thunberg.

The picture in question shows children working manually to cultivate crops.

One person tweeted: "What it is, right, is that actually she's a time traveller, and she's come to warn us about the future. It's the only explanation."

While another wrote: "Wow. Uncanny. That's scary!"
