No, Greta Thunberg is not a time traveler.
But she may have had a doppelgänger over a hundred years ago.
That is the latest conspiracy theory going around after an unearthed University of Washington photo of a girl resembling the teen environmentalist surfaced online.
The vintage photo, assumed to have been taken around 1898, features three Canadian children working at the Dominion Creek gold mine in the Yukon Territory.
Upon first glance, one of the children looks almost completely identical to Thunberg.

Twitter leapt at the opportunity to joke about the supernatural Swedish high school student.
So, ‘Greta Thunberg’ is in a photo from 120 years ago, and it’s my new favourite conspiracy. Greta’s a time travell… https://t.co/aEl9dWJ3Le— Jack - J.S. Strange (@Jack - J.S. Strange)1574106358.0

@GarethOCal That’s a tad freaky and cool all at once.— Angela Stack 💻 (@Angela Stack 💻)1574281381.0
PEOPLE said that Facebook user Allison White may have been the first to make a connection to the Swedish activist after spotting the photo hanging somewhere at Seattle's bustling Pike Place Market.
White posted this photo on November 9, with the caption:
"#GretaThunberg is a TIME TRAVELER."
References to the 1985 film Back to the Future were aplenty.

Thunberg, 16, is best known for her passionate confrontation with global leaders at September's UN climate change summit.
She accused them of being more concerned about making money rather than helping to reduce harmful carbon emissions that dramatically raises global temperatures.
"This is all wrong. I shouldn't be up here. I should be back in school on the other side of the ocean."

@PrisonPlanet Since she showed up again does that mean we can call her re-Greta?— Mark Smith (@Mark Smith)1574183597.0
The fearless environmental activist did not hold back when confronting leaders for not stepping up and saving our planet.
"Yet you have come to us young people for hope. How dare you? You have stolen my dreams and my childhood with your empty words."

The influential activist began a weekly solo school strike last year demanding more action from the Swedish government on climate change.
Because she refuses to fly due to large carbon emissions from the aviation industry, she crossed the Atlantic for this year's UN Climate Action Summit via a zero-emissions sailboat.
Based on her impassioned speech, it appears Thunberg's confidence and wisdom belie her age.
Or perhaps she is the same girl from the 120-year-old photograph, which would make her a vampire or a Time Lord or...?
So, what's your theory?
