It is important to differentiate between speculative ideas in science fiction and actual scientific knowledge. While the idea of aliens using humans as vessels can be intriguing and entertaining in fictional works, in the absence of evidence, it remains a speculative concept rather than a scientifically supported hypothesis. As scientific knowledge evolves and new discoveries are made, our understanding of the possibilities of extraterrestrial life may also change. But until concrete evidence emerges, any claims about alien interactions with humans should be regarded as speculation rather than established fact.
