Not Sure What We Are Arguing About

Mark Eby — 1/21/2006 8:06:42 PM (archived)

Just in case it wasn't clear, I think the idea that microbes or any other form of life can live unprotected in space even in a suspended state is without any scientific basis. I also think there no evidence to claim life on Earth came from elsewhere.

HOWEVER

The possibility of interplanetary panspermia seems to have scientific credibility based on much recent work including geochemical analysis of ALH84001. If you don't know this you aren't paying attention.

I would also prefer Mars life to be original as we would learn more from it.

Protected transport of life inside comets between stellar systems is highly speculative without any firm basis, but not beyond reasonable conjecture as a low probability event IMO. Only a few orders of magnitude less probable than the evolution of intelligence IMO.

Regards,
Mark
