Why is there no mention of dinosaurs in the Bible?

Christians like to say that the Bible doesn't contain things like dinosaurs because it's not a science book, but you know what? That's what would impress someone like me, is if an ancient book written and compiled by Bronze Age humans had some scientific information that we know to be true now, but nobody could have guessed at 15 zillion years ago. Maybe throw in the actual distance between the earth and the sun, or the diameter of the moon. Something none of the Bible authors could have figured out. I would accept that as proof that the Bible was inspired, or maybe even dictated to humans by god.

And the thing is, if God is real, he knows that. He knows that's what it would take to convince me that he is real, and that Christianity is the one true religion.

So why won't he do that? He could even do it right now. He could retroactively do it, but he chooses not to. Why?

The conclusion I must reach inevitably is that he doesn't like me. If God is real, and he knows what it would take to convince me, and he still won't do it, he doesn't want me. He thinks I'm not worth it.

Or he doesn't exist.
