This is an old thread, but I will reply anyway. In response to the dinosaurs perishing in the flood, that is contrary to what the bible said. The bible said 2 of each animal, not 2 of each animal except some, or 2 of most animals. Dinosaurs are never mentioned in the Bible because they were unknown at the time.
Narwhailst are you sure Dinosaurs are not mentioned in the Bible?
The oldest book in the Bible is Job, older than Genesis, how do we know this ?The Hebrew words are strange, older in meaning and suggests Moses copied Job from stories recorded before flood times. Genesis was written as a book later than Job in time, but is of course the story of the beginning .
In Job, there is talking of Dinosaurs' God speaks to Job and the friends, so in context they saw them as animals...
Job 40:15 ¶ Behold now
behemoth, which I made with thee; he eateth grass as an ox.
16 Lo now, his strength is in his loins, and his force is in the navel of his belly.
17 He moveth his tail like a cedar: the sinews of his stones are wrapped together.
The Hebrew word behemoth means "beast" in a plural sense, a very large beast. The description tells you its a Brontosaurus like creature....
Most Dinosaurs were smallish reptiles only a very were larger than Adam, so taking on immature animals say up to 9 years old, may have been God's design, for Creation Science tells us that younger reptiles could reproduce at young ages.
Hope this helps...
