Wont micro-organisms quickly adapt and start producing UV resistant strains?

There is a giant orb in the sky that emits UV and has for billions of years.

I think the microbes are still trying to figure this one out.

You are correct, however most of the harmful rays get filtered out in the upper atmosphere. Far-UV doesn't reach Earth, only UV-A and small amounts of UV-B (if the ozone layer is more or less intact that is!).
