Life on
Earth may have its origins in outer space, according to Nasa research.
Scientists
have analysed meteorites that formed billions of years ago before falling to
Earth.
The
carbon-rich fragments were found to contain chemicals similar to one of the key
components of DNA, the building blocks of life.

Tests show
that the presence of these chemicals cannot be explained away by Earthly
contamination, suggesting DNA’s origins may lie in outer space.
The find
comes from U.S. scientists, predominantly Nasa researchers, who analysed the
chemical make-up of 12 meteorites.
Writing in
the journal Proceedings of the National Academy of Sciences, the researchers
said their find has ‘far-reaching implications’.

The study’s
lead author, Dr Michael Callahan, of the Nasa Goddard Space Flight Centre in
Maryland, said: ‘With meteorites and comets impacting the early Earth, it appears that they did
deliver some very important ingredients.’
Previous
studies found meteorites harbour the other two of the three basic ingredients
of life.
These are
amino acids, the ‘beads’ that form proteins when strung together, and chemicals
needed to allow cells to create a membrane barrier. The chemicals in DNA are
the third.

In this
fascinating personal interview, Inelia Benz talks to Project Avalon's Bill Ryan
about her life and her mission to this planet.
It's an
extraordinary story, and many people who have seen this video have been very
moved and inspired. The subjects Inelia discusses go to the very heart of who
we are, and the situation we are in. Of all the interviews Bill Ryan has done
in Project Camelot and Project Avalon, he considers this may be the most
important to date.
A comment
I'd like to make: for some, watching this entire video from beginning to end
may be a transformational event. Don't be surprised if you find yourself
feeling emotional, moved, inspired, elevated, or having new realizations about
yourself, about reality, or about any aspect of what's going on in the world. This
is the territory we're journeying in.
