Regardless of genealogical gaps (which is not a huge issue), do you hold to young earth creationism?
That would depend on your definition of "young."
IOWs do you hold to the entire universe being made say, 6K to 10K years ago?
I have no biblical evidence to suggest otherwise.
Do you believe
Genesis 1:1 happened approximately 6K to 10K years ago?
I have no biblical evidence to suggest otherwise.
Or do you believe its occurrence is unspecified in regard to all other dating information (genealogies, etc.) in the Bible?
As I don't believe the ethnologies are genealogies and that Genesis does not specify when creation took place, I cannot be dogmatic. When God says something, I believe it. When God is silent on a subject so am I.
Would you describe yourself as a young earth Creationist as Dr. Barrack does.
That would depend on who I was talking to, and that person's definition of "young."
And even if you don't like the term, being too relative, do you essentially believe what young earth creationists believe.
That would depend on what young earth creationists believe. As far as I know there is no universally held position by those self-identifying as young earth creationists.
As I limit my understanding of spiritual truth to spiritual things, such as the bible, I cannot be dogmatic about the age of creation.
Could it be 6,000 years? Yes. The bible doesn't say.
Could it be 10,000 years? Yes. The bible doesn't say.
Could it be 100,000 years? Yes.The bible doesn't say.
Could it be 1,000,000 years? Yes. The bible doesn't say.
Could it be 10,000,000,000 years? Yes. The bible doesn't say.
Could it be 4.5 billion years? Yes. The bible doesn't say.
But judging from other indications I would be very surprised to find creation is older than 10,000 to 100,000 years.
