It isn't really the job of "young earth people" to convince you, or anyone, that what God said in His word is what He intended us to know. Where I think some people get off track is by imagining that the created world must match our own understanding instead of believing what God said plainly and clearly. To label people as "young earth" assumes that we blithely skip over the scientific evidence that "proves" the age of the earth is more than six or seven thousand years old. Instead, there are numerous explanations that demonstrate the universe was created out of nothing - ex nihilo - and that it was created having an apparent age. Adam was created fully formed as a grown man and Eve a grown woman. It is perfectly within the power of Almighty God to do so. This is why when He says "evening and morning", He means a twenty-four hour literal day - He had no reason to NOT reveal the truth about what He did and when He did it. He said, and Jesus reiterated, that He created the world in six days. I choose to believe Him.
The danger in attributing everything as potentially allegorical is that it negates the literal as the primary sense with allegory as secondary. What I find is that God does a pretty good job of helping us know when and which is the sense of revealed truth and we don't need to worry that we are missing something. The Holy Spirit is who teaches us the truth and opens our eyes to the lessons God desires we know. Agamemnon did a pretty good job of explaining how in the creation story God meant a literal day as the organisms were dependent on each other to regenerate and their beginnings happened closely to each other, not separated by thousands or millions of years. It's no mystery that plant life requires carbon dioxide from carbon life forms and give off oxygen that carbon-based life forms require to survive. Their simultaneous creation is unmistakable.
It isn’t really the job of “young earth people” to convince you, or anyone, that what God said in His word is what He intended us to know.
But I also do not buy anything that does not sound right to me.
And I see nothing at all that prove a literal six days, in fact I see just the opposite.
