why do scientists look at rocks on the surface of mars if life is most likely underground and away from the weather, because the rocks have been eroded so much its unlikely to find anything on them that could show signs of life so why don't they dig in to the ground instead?

A) it's hard to move digging equipment to another planet. Think how much time and money it took to get a couple of remote-controlled cars out there - now try to FedEx a backhoe.
B) Because the rocks themselves will still show signs of conditions that would allow for life to form.
Before wasting time on finding out whether there's life on mars, our first choice should be to figure out whether there was ever even a possibility of life.

Actually, the rover Spirit has been doing quite a bit of digging lately. The bearing on one of its wheels is stuck, so they've been using the stuck wheel to dig. It works quite well, and they've made some interesting discoveries with it.

They will... One step at a time. First they have to decide with precision where to look. You just don't go out and dig anywhere.

They are doing what they can with the small, light explaration robots that they have. They have drilled into rocks.
