Did the flood cover all the land?

Genesis Chapter 7

There is loads of debate about such remote ideas as “Did Noah’s flood cover all the earth so the tallest mountains were under water” if so where did the water go, “Did the bible take this story from ancient Babylonian myths”?

Or why did the dinosaurs not get on the ark?

My response is – hey guys it is a story in the bible, not expected to be historically accurate by today’s standards. For example the expression in the Bible translated as the whole earth could be translated “all the land”

Surely if the water covered the whole earth to cover even the highest mountains it had to go somewhere and there is not enough volume in the earth or the atmosphere to take all the water, so perhaps the flood did not cover literally (from our modern viewpoint) the whole earth, however there have been major flooding events in the history of the planet, for example the flood that turned Britain into an island. 

Perhaps Noah is one of the last? 

For me the dinosaur question is actually rather unimportant if you believe the days of creation are not 24 hour time periods but rather epochs - the fossil record shows life back to 200 million years ago and beyond, the dinosaurs possibly belonged to an earlier "day" and were naturally extinct before the Bible was written. the Bible concentrates on mankind, so dinosaurs would not have moved the plot along very much.

There may be similarities between Noah's ark and the Babylonian myth, and I honestly don't much care if neither or both tales are true. For me the message is that God did not forget Noah and family on the ark 

Of more interest to me is that God told Noah to bring 7 pairs of every clean animal into the ark, but we don’t actually find out what are clean and unclean in the Bible until Moses who does not appear until the next book!
