I agree, and there is massive evidence for a world wide flood.
Sorry, that happens not to be the case. Most experts place the flood at about 4350 years ago, and that is a time period that is well known to archaeologists (note: archaeologists, not geologists).
If there was such massive evidence it would be easy to find. It has not been found. Instead, there is massive evidence that no such global flood occurred at about 4350 years ago.
Question for you. About 97% of all the water on the planet is salt water. If it rained enough to flood the entire surface of the planet to a depth of tens of thousands of feet then all that salt water mixed with the fresh water and polluted it. So what did Noah drink once all the water receded?
