There was no global flood. The idea of flooding the entire planet makes no sense since the earth back in those days had not been populated "worldwide" and the confusion of mankinds languages did not occur until AFTER the flood.
So what was out there "worldwide" that was evil and bad that had to be wiped out? Nothing!
It is obvious that the flood of Noah's day was a "localized" flood. All of mankind in those early days of our history on earth lived in one small section of the globe and that PLACE was THE WORLD. It was their world; their environment. It was that world that was flooded away.
Most persons overlook what the ENTIRE WORLD was at its creation: It was all water! It was a "watery deep" and dry land appeared out of that water. So the water (the oceans) were in existence long before Noah. (Genesis 1:2)
The Noachian flood as taught by the religious system called by men is one of the many lies taught and pushed off as truth.
All by itself, Christianity makes the Creator and Most High God appear unwise with their nonsense.
The water was there long before there was aquatic life, animals and man.
