A courageous boy from New Jersey received a letter of support from NASA after he applied for the role of planetary protection officer.
Jack Davis, 9, applied for NASA's new position that was listed this week in hopes of finding help to protect the Earth against aliens, the Daily Mail reported.
In official terms, the position involves the assistance with the "avoidance of organic-constituent and biological contamination in human and robotic space exploration".
It adds that "space flight missions may intentionally or unintentionally carry Earth organisms and organic constituents to the planets or other solar system bodies".
Jack was one of the first applicants to apply, writing an adorable letter explaining why he was qualified for the job.
"My name is Jack Davis and I would like to apply for the planetary protection officer job," he said in the letter.
"I may be nine but think I would be fit for the job.
"One of the reasons is my sister says I am an alien also I have seen almost all the space and alien movies I can see.
"I have also seen the show Marvel Agents of Shield and hope to see the movie Men in Black.
"I am great at video games.
"I am young, so I can learn to think like an Alien."
The youngster signs off the letter giving himself the title "Guardian of the Galaxy".
The fourth grader would soon hear back from eminent Dr James L Green, the director of NASA's planetary science division.
He said: "I hear you are a 'Guardian of the Galaxy' and that you're interested in being a NASA Planetary Protection Officer. That's great!
"Our Planetary Protection Officer position is really cool and is very important work. It's about protecting Earth from tiny microbes when we bring back samples from the Moon, asteroids and Mars. It's also about protecting other planets and moons from our germs as we responsibly explore the Solar System.
"We are always looking for bright future scientists and engineers to help us, so I hope you will study hard and do well in school. We hope to see you here at NASA one of these days!"
In addition, Jack got a call from ASA's planetary research director, Jonathan Rall, at the NASA DC headquarters.
NASA has stated that while the job role "may not be in real-life what the title conjures up", it plays an important role in "promoting the responsible exploration of our solar system by preventing microbial contamination of other planets and our own".
