Odd tangent:
I just turned 50.
I now have a decent sense of what a century is.
A full lifespan is about a century.
10,000 years is 100 centuries - a hundred lifetimes end-to-end.
That. Isn’t. Long.
And it _certainly_ isn’t long enough for everything we know happened to happen.
For example: there are hard-to-dispute geologic characteristics indicating “Pangea” existed, and broke into the continents over time. That leaves about 5-9,000 years for the Ark’s kangaroos to head for what would be Australia AND for Australia to move some 5-7000 miles away. Given that current continental drift is measured in inches per year, the initial post-Flood continental velocities would have to be ... hard to take seriously.
Stop it...you’re embrassing yourself.
