More than 185,000 people have signed petitions calling to stop Jeff Bezos from returning to Earth after $4 on Tuesday.

Bezos, the founder of the space-exploration firm $4, said on June 7 that $4 aboard the company's $4 on July 20 in its first flight carrying people.

Three days after Bezos' announcement, two petitions launched to try to prevent the billionaire's reentry to Earth.

More than 163,000 people have signed $4 titled "Do not allow Jeff Bezos to return to Earth."

"Billionaires should not exist ... on earth, or in space, but should they decide the latter they should stay there," the petition's description said.

Some signatories gave a reason for signing the petition, which included comments such as "being let back into Earth is a privilege - not a right," and "Earth don't want people like Jeff, Bill, Elon and other such billionaires." This appears to be a reference to Bill Gates and Elon Musk, CEO of SpaceX.

Another $4, called "Petition To Not Allow Jeff Bezos Re-Entry To Earth," has accumulated more than 22,000 signatures.

Jose Ortiz, who set up the petition, said in the description that Bezos was "an evil overlord hellbent on global domination."

"The fate of humanity is in your hands," Ortiz also wrote.

Both petitions had been seeking 25,000 to 50,000 signatures, which would make them two of the top-signed petitions on Change.org, according to the website.

Bezos is taking a $4 in New Shepard alongside his brother, as well as an 82-year-old aviator called $4 and 18-year-old $4 from the Netherlands. They'll be strapped into a dome-shaped capsule, which sits on top of the rocket booster.

Once New Shepard reaches the Kármán line - an imaginary boundary 100 kilometers, or 62 miles, above the Earth's surface - the capsule is designed to separate from the booster, reenter the atmosphere, and float back down to Earth with the help of parachutes.

"I want to go on this flight because it's a thing I wanted to do all my life," Bezos said in a video $4 on June 7. "It's an adventure - it's a big deal for me."
