Another Person’s Theory....
God did not intend man to go down certain paths, Humans and Angels mixed bloodlines and also the animals became currupted, that is why they were wiped out apart from Noah and his Animal filled Ark. Then came the Tower of Babel one top of that and God confused the languages and spread man out across the world, that is why we find similar pyramid cultures across the Globe and many tribes that still tell of the great flood.
What I am saying is, were Dinosaurs experiments too, and if so did God wipe them out too during Noah’s flood. There were said to be Chimara’s which are humanoid animals? There are a lot of stories with Greek gods and Egptian animal gods taking both human animal characteristics.
The Bible view is that fallen Angels wanted to breed with humans to save them selves and it was Satan’s plot to stop Christ being born in the Flesh which meant Angel DNA was the saving factor over human DNA bloodlines but God knew this and decided to wipe them out and only Noah and his family were the pure lines for us humans to be saved as a species.
It occured several times too after and will probably occur today with DNA testing and hybrids.
Some dinos appear to have been ocean based creatures, in which case, I’d assume the Noahic flood wouldn’t have killed them.
