No but I question whether God did it. He was out to destroy mankind, not the earth. It does NOT say a height of 15 cubits at its highest point. It says all the mountains that he could see were covered. They could have been a mere 2000 metres high.
Go find a place where there are no others, no noise, no distractions.....Get on your knees and talk to GOD with all the seriousness and humbleness you can muster.!
