Hi Rob, List,

In regards to your statement... Maybe I'm wrong, or misunderstand...

"...Mark stated (quite clearly, I thought) that all life on earth gan be
genetically linked to earth and it seems far more likely that it began
here where conditions are ideal than it being delivered here by
something else...."

Does that mean that all life that is present on Earth today is
"genetically linked" to the Earth and that in itself proves it
originated here?

Are you open to the possibility that SOME of the life here on Earth
present day, quite possibly could have come from "out there" beyond our
own little rock of a planet?

Do you NOT believe in the theory of Panspermia or rather the idea that
dormant, living microbes can be transported between planets and systems
by ejecta debris from other planets?

Don't you think that sometime in the last 4.6 billion years since the
beginning of our planet that at least one piece of the "living debris"
has slammed into our planet?

Hmmm... Sounds like I believe in Panspermia, but I don't fully because
it implies that all life (on Earth) came from "out there".

I don't believe that ALL life that is presently on Earth originated
here. Perhaps over millions of years SOME of it has "adapted" not
evolved, to our planet. Creatures adapt to their environments all the
time. What's to say that something that landed here 10 million years ago
didn't adapt into something that could be genetically similar to all
life on Earth?

What if ALL life everywhere in the universe conforms to the same basic
genetic structure? Wouldn't this make the Earth based idea moot, and
suggest it's very likely that we're not in fact the center of the universe?

Regards,
Eric
