Hibiscusfire I am curious about some of your comments:
Noah carried some baby dinosaurs on the ark along with all the other animals
I don't recall mention of Noah taking "baby" creatures on the ark (please feel free to refresh my memory of the biblical passage) so how do you know this to be true?
After the flood, the climate changed and the large ones, which depended on lush, swamp-like environment, could not survive.
How do you know the climate changed after the flood which illiminated "lush, swamp-like environments" around the globe. And if they were illiminated around the globe then at what point in time did these environments return since they are abundant globally in tropical zones?
Smaller ones became more scarce as man populated the earth
Since many small creatures have survived as man populated the earth why did the smaller ones (dinosaurs) not?
Today, they are like the grizzly bear, only a few are alive in remote wildernesses far from civilization.
If what have said is true, that they are like the Grizzly bear today, then why do I not see them when I am visiting the garbage dump in Alberta, Canada? Grizzly bears are not far from civilization, as you claim, rather they can be viewed along side civilization in the U.S. and Canadian west. Even where I live (in Central Canada) we have recently had the very shy and timid Black bear venturing into the Greater Toronto area (population 5 million) in the last two months. We have not had to call the local Animal control for the dinosaurs (yet).
