pete and Iona,
To retain any credibility RE science, I must insist again...
What evidence (specifically) would be required for you to abandon your belief in YEC?
Please provide this for us.
If you do not, you highlight the chasm between science and religion.
This is not a trick question.
It is THE question.
If you cannot answer this question, we know that we are speaking different languages.
You are arguing religion, and some of us are arguing science.
Without your specific answer, we cannot continue to try to meld these conversations.
So, answer the question, or admit that you are not talking science.
Sorry, but those are the only options.
And I totally respect either answer you might give (if you give an answer).
