Mars Probes Vanish!

Being somewhat of a science buff I find it interesting to follow the news of all the various probes and satellites we have circling the Red Planet. However, it strikes me as odd that various "unexplained" things have been happening. A Martian probe had discovered the supposed crash site oof another martian probe but when the probe went to look a second time the supposed crash site had vanished! Another Mars probe was looking into the possibility of life on Mars by detecting methane in the atmosphere combined with water. As the probe went to examine this intriguing area where an abundance of methane was detected that probe too vanished! Of course, we all know methane is created by farting. It is a highly unstable gas that won't exist on its own for more than a couple hundred years. I suspect there are intelligent life forms on Mars trying to deter us from discovering their identity and they are causing our probes to crash! On the plus side, one of the Martian rovers was so covered in dust that it was nearly non-functional. Then, one night, all the solar panels were mysteriously swept clean! Scientists have no explanation. Could there be intelligent creatures on Mars? Or is it more likeley that out space program is inept? Or a combination of all three?
