Is Mars the key to our origins ?
In 2012 Nasa's scientist started searching for evidence that Mars
have life. They sent 14 probes and they failed before its sending any data.
Viking missions were carried by Martian soil and some of them gave positive
results of living organisms and the others gave negative results. Also they
found evidence of weird chemical reactions, but not life. In the mid of 1990's scientists found bacteria
living total darkness far below the surface and also the discovered infection
proteins that makes copies of themselves without the need for genes.
Some scientists think that the life on earth was originated by Mars
because there is some common things such as reproducing structures relatively
made from complex organic molecules. Mars life forms may then have left the
planet inside meteors catapulted off the red planet by cosmic impacts. The
scientists have found approximately 100 meteors from mars their origin proven
by a small pocket of gas corresponding to the atmosphere of Mars. Curiosity may
do more than expose weather Mars has ever a life. (172)
