I'll quote one of the Daily Creationism's recent posts about the Flood (not Halo):

The Bible says that about four thousand years ago water covered the entire earth! There would of also been many volcanic eruptions because the Bible speaks about the mountains of the great deep breaking up. What a catastrophic event!

If Noah's flood were true then you would expect to find some evidence for it. You would expect to find something like billions of dead things buried in rock layers laid down by water all over the earth. And what do we find? We find billions of dead things buried in rock layers laid down by water all over the earth.

Well ignoring the fact we don't find any evidence for a global flood, ignoring the fact that there isn't enough water to flood the whole planet, and ignoring the problem of where did all the water go, ignoring the fact that most water going species that have existed also apparently died in the flood (may be they forgot how to swim), ignoring the fact that the civilisations around at the time; Egypt and so on, aren't affected by this world wide flood and don't record it. Ignoring all that I'll just deal with one little problem I see.

How do creationists explain the fact that we find older species deeper in the earth and newer species buried closer to the surface? I would of thought a flood that wiped out virtually all life on Earth (you worship a god that did that?) would result in everything being pretty much randomly distributed.

We would find humans with dinosaurs, and so on. Yet we don't see this, we always see the same species together, but not separate species. We can see a distinct historical timeline, with some groups of species together, yet higher up in the strata we see completely different species and no more traces of older species.

What's your working solution to this inconsistency?
