Hi, Crashman, and welcome to EvC.
It would certainly be very interesting if Europa did have life. Assuming that there was no panspermia involved, the implications of abiogenesis happening twice in the same solar system are that life must be common throughout the universe. And, although multi-cellular life might still be rare, and intelligent organisms even rarer, it would greatly increase the chances of their existence elsewhere.
So even finding traces of extinct microscopic life forms somewhere in the solar system would be the find of the century.
Welcome again, and don't hesitate to start a thread on String or M Theory, if you can put it in terms that non-physicists can understand!
