Martian rock found in Morocco

It is hard for me to imagine that a rock from another planet somehow landed on Earth. The one found recently in the Saharan Desert was about the size of a baseball. But not just one rock but around 65 have been found in Morocco and in Antarctica of late. Inside this meteorite was water. If there is water then there must be life, don't you think? It is selfish to think that we are the only life "out there". The age of the meteorite was estimated about 2 billion years ago. Researchers performed a battery of test on the meteorite and based on its chemical signature confirmed that it came from Mars.  More test are under way to see how long it was in the Saraha and how long it was floating in space.  Very interesting stuff, I must say.
