Hi Shane,
Silicon based life form was a sci fi movie back in the 60's. Can not remember much else about it.
Si based life form would still be recogizable. I was tending toward something that is not.
How far does research have to go to prove a point? Just because there is very little or no evidence of alien life does not prove either way. If we find nothing then where do we draw the line?
Think about this: If alien life is found, what kind of stimulation of research activity would occur? I believe it would be massive. What are the consequences?
Cheers
