It can't be so difficult to do, eh? Have you tried it?

People are engaged in projects of this sort. The QED project, Mizar, etc.
It's not as trivial as you make it sound. Take a look at the following two
links to get a sense of the state of the art.

While I do believe that eventually we'll reach the point where machine
checking of proofs will become routine, we're simply not there yet. A lot
more work needs to be done.
