Our DNA came from space, says a scientific study

We know this for sure. But there are still many opinions about the origin of life on Earth. Some scientists say that it originated on Earth, while others say that life was ‘brought’ to Earth by celestial bodies like meteorites and comets.

Now, a study has put forth an interesting argument that DNA, the very building blocks of life, originated in outer space. The study has been published in the journal Nature Communications. The researchers have found presence of nucleobases, compounds that form the DNA, in meteorites.
