Is panspermia a scienctific theory?

[Trantor]

I'm pleased to see support for my earlier insistance that panspermia is a scientific theory (in contrast to ID) in the fact that a summary of the status of this theory is in the current edition of "Scientific American".

To quote: "As we have show, panspermia is plausible theoretically. But, in addition, important aspects of the hypothesishave made the transition from plausibility to quantitative science".
