SCIENCE! Aliens on Mars!

I know what you guys might be thinking but no you are absolutely incorrect sir. I stumbled upon a article that may prove that there could be alien lifeforms on mars. The zinger about it is…..we put them there. A mistake made at N.A.S.A. about putting on the drill of the Mars Rover Curiosity, could have broken containment and let hundreds of thousands microbial stowaways on board. If the Rover finds water, there is no guarantee that if it finds some form of bacterial life, it could be martian or earthling in nature. Heres the link to the article for further reading. http://www.dailymail.co.uk/sciencetech/article-2201628/Lets-hope-DONT-water-Mars-If-Curiosity-finds-H20-end-contaminating-planet-microbes-survive.html?ITO=1490
