But when looking from a creationist's perspective where the earth is only a few thousand years old.
But it isn't a few thousand years old. It's been known since 1820 or so that it's a thousand or more times that old, and ALL scientific evidence confirms that - about 4,560,000,000 years old since it accreted from protoplanetary objects, to be more precise. And no matter what the dates say, there are no worldwide deposits all dating to any one event anywhere in the geologic record. A "great flood" in the last 5000, or 500,000, years would have left some trace. It's not there.
