No one is saying that Homo sapiens climbed out of their spaceships fully formed on planet Earth one day. We obviously spent a lot of time evolving on Earth.
However, scientists have difficulty tracing our most distant origins—that is, our basic building blocks. Even though it sounds straight out of a science fiction movie, it’s hypothesized that life, including human life, initially came from outer space. That’s right, aliens may be our ancestors.
Panspermia, the transfer of viable organisms between planets, is considered a serious hypothesis by planetary scientists. It seems utterly bizarre, but this idea is so highly regarded in the scientific community that it’s being funded by NASA, MIT, and Harvard, to name a few.
