Dinosaurs are mentioed in the Bible, actually!
Ummm...No.
Actually Genesis falls down pretty badly in its description the formation of the universe, stars, our solar system, the Earth, and the evolution of life.
E.g.,
Day 3: "Let the earth put forth vegetation, plants yeilding seed, and fruit trees bearing fruit in which is their seed, each according to its kind upon the earth".
Day 4: ”And God set them in the in the firmament of the heavens to give light upon the earth.
Day 5: "Let the waters bring forth swarms of living creatures, and let the birds fly above the earth across the firmament of the heavens".
This does not follow the fossil record. The ancestors of the flowering plants (angiosperms) first appeared at the close of the Mesozoic. The lower Mesozoic rock is devoid of angiosperm fossils. Such fossils begin to appear in the strata of the Cretaceous period and in greater numbers in the early Cenozoic.
The earliest fossils appear to be from thermal vents or hot springs under the ocean which are approximately 3.2 billion years old.
Yeah, it's right next to the verse Bill Clinton found that says oral sex is not adultery.
I'm not being flippant, either. People (deliberately or subconsciously) read into the Bible anything that they really want to be there, and read out anything they don't. If you can't find a mention of Martian bacteria, either you aren't trying hard enough or you just don't want such a thing to exist.
