Hello.
Interesting converstion. I thought I might add the following:
To put it in perspective, if you argue that the age of the Earth is only 6,000 years old, that means you have to be prepared to say that Noah's flood happened roughly 2400 BC... at a time in which some of the great ancient kingdoms of the world, such as Egypt, were in existence and having thriving dynasties.
I don't know about you, but I'm not personally comfortable dating Noah's flood to only 2400 BC.
I'm very much a champion of taking the Bible literally, and for that I believe in a literal creation, and even a young earth. But I have read in some scholarly literature that there are ways of counting the years in Genesis that would actually put Adam and Eve back in the Garden roughly 20,000 years ago.
Such a reading, I think should be prefered.
If we are to understand the Bible in a literal-historical-grammatical way (as I believe we should), then we need to read the Scriptures in their actual "historical" context. Adam, Eve, Noah, etc, were all historical people, and we should be able to date their existence into the actual history of the world.
Being that what is recogniezed as modern civilization and recorded history began to take root about 6,000 years ago, it seems to me only logical to believe Noah's flood would've happened some time before then. Indeed, if a universal flood happened (as I believe it did), then such a flood would've destroyed most of man's written record about himself. Such would explain why prior to 6,000 years ago, we have little account of mankind, and what evidence we do have is very scant and scattered. It's mostly fragments of broken pottery, tools, buildings, and other such things (they are things that would survive a flood.)
If we believe the Earth is only 6,000 years old, that means Noah's flood would've happened in 2,400 BC according to some accounting methods of Genesis's genealogy. Such doesn't seem to fit the historical record, which would suggest to me that our accounting methods might be off a bit.
In 2,4000 BC, Egypt was a developed nation and was in the middle of its great dynasties. No flood seems to have happened in 2,4000 BC that wiped out Egyptian civilaztion, or caused them to reboot their order of kings. They seem to have been just fine and without interuption.
So, using some accounting methods of Genesis places Noah's flood during this time period. Such seems impossible to do if we hold to thie historical-grammatical interpretation of Scripture. Therefore, I think we might need to revise our accounting methods in our reading of Genesis in order to better date the history of the Bible and world.
I could be wrong in my interpretation. But there is nothing specifically in the Bible that says the Earth is only 6,000 years old. That's something that has been determined by reverse engineering the genealogies of Genesis using a very specific accounting method... a method which some scholars have disputed. Some have championed other accounting methods and ways of literally reading the geneaologies of Genesis, which takes us back much further than 6,000 years, and possibly as far as 20,000.
Exactly how old the world is, I'm not sure. I don't believe it's billions or millions. But I don't believe it is only 6,000 either.
