They will now, but until Mt. St. Helens blew, they generally didn't believe that many layers could occur at one time. Before that, they assumed that the layering within the rock, meant ages.
So now they are a little more careful before they make that assumption.
As far as Asimov, Jesus considered Moses works to be authentic. That's good enough for me. If you want to throw the whole religion out the door, then certainly I'm at a loss to prove Moses actually wrote the first five books. But if you accept Christianity in part, then it seems to me, to be inconsistent, not to take note of Jesus' reference to the works of Moses, and to the flood. And I bring up the flood, because most long agers, throw the flood out, completely. Why on earth they still believe in Jesus when they just made Him into a liar, I don't know.

Excuse me? I remember reading years ago that Mt. Fuji laid down most of the Kanto Plain in a single eruption. I don't think you're correct there at all.

You want to show me where in the Scriptures we learn that Jesus couldn't tell a parable or an allegory from a literal account of facts?
Perhaps you think Jesus read, "There is nothing new under the sun" in Ecclesiastes, and decided that when a sandal-maker made a new pair of sandals he was actually making an old pair of sandals.
"Why on earth they still believe in Jesus when they just made Him into a liar, I don't know."
Extending and applying your line of reasoning, Our Lord made Himself into a liar when he said, "I am the good shepherd." He didn't keep sheep.
