Are you aware that tsunami deposits are largely UNSORTED rubble with
particles of all sizes? That is NOT what we see in the geologic
column. We see excellently sorted particles, and microscopic fossils
sorted by either their shape or their exterior patterning on the tests
(shells). Why only animals with certain patterns are deposited at one
period during the flood remains a realy mystery to me and was one of the
things that eventually led me away from YECism.

Why could astroids only hit the water? Did the land have asteroid
blasting lasers that kept them at bay? Anti-asteroid cream? And
besides, the large tsunamis, come on shore rapidly and bury LAND animals
(and drag some of them out to sea). The land and marine animals should
be mixed up in this model. Hundreds of New Guineans were sucked into
the sea after their tsunami.

So where are all the land animals that are on land when the first waves
hit the beach. YOur model should predicts a fossil order of 1. land
animals 2. marine animals. This is backwards to what we see.

YOu are an unusually(unreasonably/blindly) optimistic fellow. You are
suggesting that NO explanation is a reason to believe your view.
