A controversial new study is making waves worldwide with a staggering claim, that fragments of “alien” DNA may already exist within human genes. According to the researchers behind the report, certain mysterious sequences in our genome do not match any known terrestrial origins, leading them to speculate that they could have been inserted into human DNA millions of years ago.
The study suggests that these genetic anomalies might be remnants of panspermia, the hypothesis that life, or at least its building blocks, arrived on Earth from outer space. These segments of DNA, the authors argue, may hold clues about humanity’s deepest origins and potentially link us to life elsewhere in the cosmos.

Critics, however, have been quick to call the claims “bonkers” and highly speculative, pointing out that unexplained genetic sequences are not necessarily alien in nature. Many scientists argue these could be ancient viral insertions, undiscovered microbial signatures, or errors in sequencing technology rather than evidence of extraterrestrial tampering.
Despite the scepticism, the study has reignited a global fascination with the possibility that humanity’s story might be far more cosmic than previously thought. Could our genes carry hidden messages from the stars, or are these findings simply misunderstood anomalies in our complex DNA?
Whatever the truth, the idea of “alien DNA” living inside us has captured the public imagination, blurring the lines between science fiction and science itself. This bold claim underscores how much we still have to learn about our genetic makeup, and our place in the universe.
