- Despite the incredibly extensive study of the origins of life on Earth, we're still not sure exactly how our planet's first life forms were created.
- It's possible, many scientists say, that life on Earth may have originated elsewhere.
- Right now, the leading candidate for a source of life that may have seeded Earth is our neighbor, Mars.
How did life on Earth begin? It seems like such a simple question, but due to the billions of years that have elapsed since the first life forms began doing their thing on our planet, we simply don't know the answer. Life on our planet may have originated here, but it may be just as likely that it originated somewhere else, like Mars.
The scientific concept that life could organically spread from one planet to another is called panspermia, and it's not nearly as wild as it might sound. We already know that rocks from Mars have made it to Earth because we've found them here, but if ancient Mars did host life, what are the odds that life on Earth is a direct result of life forms being yanked from Mars and sent speeding toward Earth?
