| − | Recently, researchers have shown that natural gas can form rapidly<ref>O’Donnell, E. 2005. “Rocks into Gas.” Harvard Magazine 107, no. 4.</ref>, supporting the idea that petroleum products could have been formed within the last few thousand years and are constantly being replenished, supporting the views of [[Young Earth Creationists]]. If this research is supported it would refute the idea that fossil fuels are diminishing. It is also likely the [[Great Flood]] described in [[Genesis]] produced vast quantities of coal, oil, and gas because of the rapid [[sediment]]ation associated with the flood waters.
| + | This gives support to the creationary view. If this research is supported it would refute the idea that fossil fuels are diminishing.{{fact}} |
