I saw something the other day where they found a man-made Stonehenge-like structure at the bottom of Lake Michigan, and then another at the bottom of Lake Huron. "Science" has always told us that the Great Lakes were formed when Ice Age glaciers "receded" and dug out the Great Lakes, with the melted water causing them to be filled up. Since we live near the Great Lakes, we were indoctrinated with this in grade school as if it were certain, unassailable fact.
I also saw something about similar structures at the bottom of the Baltic Sea.
Clearly these were filled by the Flood Waters and people had lived in these places before the Flood.
What's funny for Father Paul Robinson's "Local Flood" theory is that even some mainstream scientists are coming to the conclusion that there was some cataclysmic world-wide Flood event. They claim it was 10,000 years ago, but we know that to be untrue and also claim it was caused by rising Ocean levels (for unknown reasons) ... but realize that this was no "Local" Flood but a worldwide thing.
