Could it be that there have been a bit more than 6000 years since Adam became fully human like us? to be such, he would have been expelled from the presence of the tree of Life. I haven't a clue as to how long he and Eve existed before they were expelled, but the expulsion should time out to about 6000 years give or take.

We ahev it on good authority that God does not create things to trick us, so the measuring systems we have tell us that the planet is about 3 1/2 billion years in existence.

Now if the 'constants' we depend upon to set our gauges are changing or have had major changes, then all bets are off. But my guess is that even the speed of light in a vacuum has slowed considerably since the beginning of the Universe. The rules of entropy tell us the Universe is cooling down, so the whole shebang has to be older than 6000 years.

Could it be that there have been a bit more than 6000 years since Adam became fully human like us?

I'm open to that possibility. I recall hearing Dr. Gene Scott discussing who Adam's kids married by saying there were people on earth before Adam. He maintained Adam was different, the first spiritual man, as opposed to the little more than animal men, Adam was different, God breathed spiritual life into him.

That's one way of reconciling a long fossil record with James Ussher's chronology.

Another is that Ussher miscalculated or failed to take some largish chunk of time into account. After all, he was a mere mortal, not an infallible author of the Bible.
