Actually we do know that. There is no evidence of a worldwide flood 4,500 years ago, yet there is evidence of smaller older floods. Logically a newer larger event should have overwritten the smaller older event. This is a case where no evidence for an event is evidence against it. That is rather rare, but in this case lack of supporting evidence is evidence against your claim.
