Photos are there for plenty of reasons. For one, people take photos to preserve memories: to capture an essence or to document a rather memorable event for posterity's sake.

Of course, photographs can also be used as evidences for something. There are people who claim to have captured beings classified as "supernatural", moving some doubting Thomases to rethink their stands on certain things.

One such example could be the recent photos taken from Mars via the Mars Global Surveyor.

The said pictures "suggest" that water has been present in the "dusty, cratered" planet for the last five years. Water's existence on Mars was being observed by NASA's Mars Exploration Program. And says lead scientist Michael Mayer, "These observations give the strongest evidence to date that water still flows occasionally on the surface of Mars."

So there's water in Mars, big deal. Well dude, here's the catch: water is quite important for lifeforms, and the presence of such may point out to life in Mars. Hmmm.. curiouser and curiouser...

But before grabbing those aluminium hats made of tinfoil and being all alien-paranoid like, better hold your reins. Oded Aharonson of the California Institute of Technology says that water ice has been detected on the North pole, and the photos may be just of those, instead of alien life form reservoirs.
