When it comes to aliens and science fiction, most films and television shows depict it as an invasion of Earth. However, one American scientist believes that aliens may be too terrified of dangerous and aggressive people to visit Earth.

Humans are dangerous, violent, and continually involved in unending terrible disputes and wars, according to Dr. Gordon Gallup, a biopsychologist at Albany University in the United States. Dr. Gallup believes in death and genocide.

In an open-access publication published this month in the Journal of Astrobiology, Dr. Gallup made his case.

According to Dr. Gallup, if extraterrestrial life exists, it may have discovered that humans are dangerous, violent, and always embroiled in unending bloody conflicts and wars, as well as constantly producing increasingly more destructive weapons of mass destruction.

It would also be self-evident that, as a result of increased pollution and habitat destruction, as well as constant wars, theft, death, devastation, and the ambition to conquer, humans constitute an unmatched and unprecedented threat not only to other species on Earth, but also to life on other planets. He adds, "planets."

Dr. Gallup uses the 'total annihilation of the highly advanced Aztec and Inca civilizations' as an example, along with the genocide of the indigenous population, demolition of their temples and buildings, and stealing of their riches and natural resources.

Could indigenous alien communities face the same fate as the natives of Mexico and Peru if humans on Earth become aware of advanced civilizations and coveted resources on other worlds?, Dr. Gallup questions bluntly.

People could be regarded exceedingly harmful if intelligent life exists elsewhere. Because we pose too great a risk and they don't want to be detected, there may be no evidence or persuasive evidence of extraterrestrial intelligence, according to Dr. Gallup.

Professor Stephen Hawking, a famous British astronomer, has expressed alarm about the hazards presented by intelligent and hostile aliens throughout his life, according to Dr. Gallup. After they have depleted their own resources, these aliens may come to conquer, enslave, destroy, and colonize humanity in order to plunder the resources of our planet.

Professor Hawking believes the outcome will be similar to what happened when Columbus arrived in America, which did not end well for the Indians, according to Dr. Gallup. However, the fact could be exactly the reverse, as aliens may be afraid of being discovered.

According to Dr. Gallup, humans are unusual in that they have gained the technological ability to trigger their own extinction.

When it comes to our reliance on fossil fuels and the consequences of climate change, people appear to be on the verge of reaching a tipping point. This track shows that, for the first time in Earth's history, we are on the verge of mass extinction caused by the actions of a single species, namely the human species, he says.

Gallup's research is based on Fermi's conundrum, which is a clear contradiction between the lack of evidence for extraterrestrial civilizations and numerous high probability estimations. To put it another way, if extraterrestrial life exists, why haven't we discovered any evidence of it?

According to Erik Zackrisson, an astrophysicist at Uppsala University in Sweden, there are 70 trillion planets in space, a staggering figure with twenty zeros after the number seven. According to researchers at British Columbia University, there could be as many as six billion Earth-like planets in our galaxy.

Exoplanets, or planets outside our solar system, have been confirmed in 3,704 systems, according to NASA. The majority of these exoplanets, like Jupiter and Neptune, are gaseous.

Dr. Gallup believes that sentient life exists elsewhere, but that intelligent, technologically complex life is the exception rather than the rule, based on the history of biology on Earth.

Despite the fact that there are billions of different life forms, records of intelligent life with complex tool-making abilities and the cognitive ability to achieve self-awareness indicate that it has only appeared once, making the prospect of finding technologically sophisticated intelligent life elsewhere exponentially remote, according to Dr. Gallup.
