Well, I did make that up myself.
I believe it differentiates those "creationists" who believe that God created all things, and that science describes His creation pretty well. Vs. "fundamental creationists" who believe that God zapped things into existence pretty much as-is.
I see no evidence that anything has changed in the last 2000 years, one thousand years, 500 years or even 100 years. Evolution appears to have stopped.
Surely at least a moneky or two would have at least stood upright within that time, grown vocal cords, learned to build a better home. or SOMETHING!. But no. In fact, of the millions of different life forms, species, not ONE has shown a hint of evolution.
If man evolved from monkeys and apes, why are there still monkeys and apes?
Why aren't there more varieties of man? there are all sorts of varieties of monkeys and apes. Spider monkeys should have brought us spider men!
There certainly were other creatures which are now extinct, and that process continues every day.
You keep trying to put God on a timeline, and that is a mistake, God is timeless, he's past present and future.
The only thing restricted to time is us, from this spot on this planet. Time as we know it, and mark it only exists here.
What is a "day" to God? God spoke and said "let there be light, and there was light, and it was good". That's when time for us began. Not for God though.
