"If there was a Biblical flood it would have occurred all over the world at the same time, so there should be lots of Grand Canyons all over. Where are they?"

Your argument can be viewed another way, too:

If the Grand Canyon were formed over millions of years by natural geological forces, they would have occurred all over the world at the same time, so there should be lots of Grand Canyons all over. Where are they?

Answer, please?

See, that's the problem with employing imbecilic straw men to try and make a non-existent point... they fall apart with the slightest breeze...

My model does not require vast amounts of water to be released over a short period, as yours does.

In my model, God created the world over billions of years, so untold numbers of Grand Canyons have been formed and obliterated through the eons. There is nothing in my model that requires lots of Grand Canyons all over at any point in time. Yours does because you only allow a compressed timespan for geologic processes to work.

Now can you address the other two points in my first post?
