Erm -- I'm pretty sure they were carbon based.  They 'oxidized' their food
using sulfur rather than oxygen, though.  But I'm not disagreeing with you;
I don't see Lynn's point yet.  It doesn't make sense to me that life could
only be carbon-based.

Where did you find the information that life on other worlds is quite
common?  I wasn't aware that any had ever been discovered.
