there is no verifiable evidence or scientific consensus regarding the existence of extraterrestrial life or any confirmed instances of humans obtaining DNA from aliens.
The idea of humans obtaining DNA from aliens is primarily a concept found in science fiction literature, movies, and conspiracy theories. While there is ongoing research in the fields of astrobiology and SETI (Search for Extraterrestrial Intelligence) to explore the possibility of life beyond Earth, there has been no confirmed contact or interaction with intelligent extraterrestrial beings.
It's important to distinguish between real-world scientific endeavors and fictional or speculative scenarios. As of now, any claims or stories about humans obtaining DNA from aliens remain in the realm of speculation and fiction rather than established scientific fact.
