AURORA, Colo. -- "Flat Earth" believers have gained internet notoriety in recent years. As the name suggests, the group believes the Earth is not round.
"Was there ever any debate when you were in first grade and you were learning about cosmology? Was there anyone who disputed it ever in your whole life but now?" said Dorothy Novak, a flat-Earth believer.
As science -- and common sense -- have proven, the world is not flat. However, flat-Earth believers say otherwise.
“Look with your own eyes. Go out to the beach on a cloudy day. Are the clouds curved?" asked Novak.
But not everybody is on board with the big blue marble belief.
"I don't believe that we are. I don't believe that there is the evidence to support it from a scientific method,” said Robbie Davidson, coordinator of the 2018 Flat Earth International Conference that's happening in Denver Thursday and Friday.
"The conference is about being able to question things and not being afraid to ask questions,” Davidson said.
Over 800 flat Earthers are expected to attend the two-day conference and discuss topics ranging from "Flat Earth Clues" to "NASA and other Space Lies."
Flat Earther "Mad" Mike Hughes raised awareness by putting himself in his home made rocket that he built and flew, all to "go to space to prove the shape of the planet,” Hughes said.
His homemade rocket didn't reach 2,000 feet above the ground, according to Motherboard. A ticket on any commercial flight is a more reasonable option for those hoping to see the curvature of the Earth.
Mad Mike hopes to someday, perhaps, be the one to prove once and for all what a few believe.
"I only want the truth. I have no agenda," Hughes said.
He also has other plans as well.
"I'm going to try and set the world speed record in a boat," he said.
The two-day conference is being held at the Crowne Plaza Hotel in Aurora.
