NASA's study of Aliens..!? Evidence on Mars?

Scientists have always been interested in researching the atmosphere and topography of Mars. As nasa continues to search for evidence of life on Mars millions of years ago, a new laboratory experiment by nasa suggests a new strategy for finding traces of extraterrestrial life.
The Perseverance rover, which is on a mission to detect the presence of aliens on Mars, should dig at least 6.6 feet or more into the Martian surface and find traces of life, according to a study conducted by scientists. Scientists say that if the rover's amino acid traces are found, it will be strong evidence that life once existed on Mars.However, the study believes that over time, evidence for life on Mars has also been damaged by cosmic rays. A study published in the journal Astrobiology suggests that evidence for life on Mars may be decaying faster than scientists previously estimated.Their findings suggest that amino acids in Martian surface rocks are destroyed by cosmic rays, and at a much faster rate than previously thought said Alexander Pavlov of NASA's Goddard Space Flight Center in Greenbelt, Maryland. The rover has successfully drilled into the Martian soil, revealing micro craters or materials less than 10 million years old, he added.A nasa study shows that alien sources may be buried deep in the Martian surface. So scientists say that only by digging deeper they can get evidence.
