Gee, one would think you would have to bury a lot of living material in order to mine these vast quantities of natural resources, huh? Maybe, just maybe, something like a global flood could create that much material worldwide and that much sedimentary rock.
No, no evidence for that. The fossils are where they should be if many living things exist over vast amounts of time, and sediment is carried by denudation. There are no rabbits in the same layer as trilobites, and there are no dinosaurs in the same layer as mastodons.
In some places on earth rivers cut deep deep ravines rather than fill up with sediment. Why? We should be able to go to these areas that are filling up with sediment and find all manner of organisms, fish, animals that are being buried. Except that process only happened billions of years ago. And nobody can say exactly how tall the mountains had to be to cover the whole flat part of the earth with miles of sedimentary rock.
Its easy to describe a process, but sometimes the very simple questions (like maybe out of the mouths of a babe) end up with them answering by saying "science hasn't proved or answered that yet"
And for them, that's okay to say science has proved or answered that yet". Because their hope is in science and that someday it will reveal everything. Our hope is in God and that someday he will reveal everything.
