I have decided that I made a substantial mistake in promoting this topic from the "Proposed New Topics" forum. I should have asked for revisions.
The geologic thoughts of message 1 are badly flawed (non-admin mode opinion). Despite or perhaps because of this, I (admin mode) thought the topic had a lot of potential for interesting discussion - Thus I got over enthusiastic and did the promotion.
I encourage you to submit a new version of your thoughts of this topic, as a new "Proposed New Topic". As per what I already said in this topic, please keep the halo considerations out of the message. They have been and are better covered in the "Dates and Dating" forum.
I do like the topic potential. But I do think it needs to get off to a better start.
I suggest
Granite as a "Genesis Rock" as the new topic title. You can mention Robert Gentry in the text of message 1.
Closing this version of the topic.
Other than the proposing a new topic, responses to this message should go to the "Considerations" topic, link below.
