Since the beginning of time, we have been told about extraterrestrial
life such as life on Mars, yet still we haven’t had proof, until now. For
centuries, we humans have inhabited the Earth and made it the place we call
home. Now, evidence of possible life on Mars has created an even bigger debate
for scientists. The real question is, are we alone?
There is a
possibility that there are microbes living on Mars. “There is also a
possibility that life began on Mars,” stated Professor Brian Cox at a recent
STEM (Science, Technology, Engineering and Mathematics) day in Lincoln.
Wherever there
is water, there are microbes, living forms that could possibly evolve, giving
us a new form of life. Probes will be sent to Mars on a new mission to look for
underground water. “There is a chance that there is water under the surface of
Mars and wherever there is water, like on earth, there will most probably be
some sort of life forms,” added Professor Cox.
NASA’s Mars
Exploration Rovers, Spirits and Opportunity, are exploring Mars. It began in
2003 and they are there in order to look at the surface and geology. Evidence
of a thigh bone was found, meaning this could lead to proof that life began on
Mars and possible evidence of dinosaurs.
But why
aliens? Why not another form of human being? Think about the word alien, the
dictionary definition is ‘belonging to a foreign country’. What’s the first
thing you think of when you say alien? We all seem to picture a short green
blob with one eye, but what could they really look like? What if we are living
amongst aliens, but we don’t notice because we all look exactly the same? Turn
to the person next to you; do you know for sure that they’re from Earth? Are we
really alone?
