Nice try. The Bible never once indicates that dinos were ever domesticated. Indeed, the Bible seems to indicate quite the opposite...namely, that even those humans who were considered mighty were quite terrified of what are almost certainly descriptions of dinosaurs:
Job 40
15 “Look now at the behemoth, which I made along with you;
He eats grass like an ox.
16 See now, his strength is in his hips,
And his power is in his stomach muscles.
17 He moves his tail like a cedar;
The sinews of his thighs are tightly knit.
18 His bones are like beams of bronze,
His ribs like bars of iron.
19 He is the first of the ways of God;
Only He who made him can bring near His sword.
20 Surely the mountains yield food for him,
And all the beasts of the field play there.
21 He lies under the lotus trees,
In a covert of reeds and marsh.
22 The lotus trees cover him with their shade;
The willows by the brook surround him.
23 Indeed the river may rage,
Yet he is not disturbed;
Job 41
1 “Can you draw out Leviathan with a hook,
Or snare his tongue with a line which you lower?
2 Can you put a reed through his nose,
Or pierce his jaw with a hook?
3 Will he make many supplications to you?
Will he speak softly to you?
4 Will he make a covenant with you?
Will you take him as a servant forever?
5 Will you play with him as with a bird,
Or will you leash him for your maidens?
6 Will your companions make a banquet of him?
Will they apportion him among the merchants?
7 Can you fill his skin with harpoons,
Or his head with fishing spears?
8 Lay your hand on him;
Remember the battle—
Never do it again!
9 Indeed, any hope of overcoming him is false;
Shall one not be overwhelmed at the sight of him?
10 No one is so fierce that he would dare stir him up.
Who then is able to stand against Me?
Yet, every knight errant in the early feudal/monarchical times thought he had to go out and “kill a dragon” to prove himself.
