Just some scientific thoughts on a worldwide flood

Just to play devil's advocate for a second (I'm aware of the irony in that statement), but why would you have such a hard time believing Noah's flood might be possible?

1. We know there is enough water to cover the Earth by over a mile if it was flat.
2. We suspect there is another oceans worth of water locked up in Earth's crust in ringwoodite.
3. We think the continents formed a super continent in the past and have since changed position drastically.
4. We have meteor impact craters like Chicxulub that seem to have altered Earth drastically.
5. We know strata layers are almost always layed down by water.
6. We know animals have to be buried fast in order to fossilize instead of deteriorate.
7. We also know that major canyons can be created rapidly (Mt St. Helens) and have no conclusive evidence of them forming slowly.

So given that, why couldn't we have an event like Chicxulub, cracking the Earths' crust so drastically that the continents broke into the pieces we have now, allowing them to sink into the water. The heat from such an impact and the massive movements in the crust could have released massive amounts of water in ringwoodite (aka: The Fountains of the Deep). That could potentially have been enough to cover the entire Earth's newly flattened surface.

Supposedly Noah's flood water covered the Earth for almost a year, which seems like a decent enough time to have massive continental shifting, causing massive amounts of dirt to be stirred up and eventually settle out of the water giving us world wide strata layers and world wide fossil and oil deposits. As the crusts continued to shift and run into each other they created new ocean basins and new mountain ranges, also potentially dragging some of the surface water back into the crust allowing it to be locked back up in new ringwoodite. Then as the water started to flow into the new ocean basins we get run off in massive quantities, cleaning sediment from some areas of the continent and carving out areas like the Grand Canyon in other areas.

Then finally all of that evaporation occurring after the flood may have created the ice age giving us rapidly changing temperatures, a few ice bridges between continents, and a few flash frozen Woolly Mamoth's

It sounds fairly plausible. Which evidence points to Noah's flood definitely NOT happening?
