The man was asked a number of questions and according to a lie detector test he is telling the truth, the Metro reported.
In 2030, the US president is a person called Ilana Remikee. He claims he has put his life on the line travelling back to 2018, all because he wants to warn us about the future.
Temperature in North America will also increase due to global warming, he said.
However, his news is not all bad. Humans in 2028 will reach Mars and cancer will be cured. Diesel cars will also replace electronic ones.
The unknown man claims he is actually 50 in a 25-year-old body after taking a rejuvenation drug.
Since there is no hard evidence to back his claims, we will just have to wait and see how the next 12 years pan out.
And if he is even remotely right, we are in for one hell of a ride....
