Here is the full question from my student: In Christian teaching, the Bible mentions God creating man, trees, light, and so on. Why does the Bible not mention Dinosaurs and cavemen?
While many creatures created by God are mentioned throughout the Bible, not every living being is listed by name. The answer to this question is actually provided in the first pages of Sacred Scripture. While its timeline is arguably hyperbole (but that’s a whole other article), the Book of Genesis recounts the creation of the universe and everything in it: Man, trees, light, and yes, cavemen and dinosaurs.
LIGHT
“God said: Let there be light, and there was light.” (Genesis 1:1)
TREES
“Let the earth bring forth vegetation: every kind of plant that bears seed and every kind of fruit tree on earth that bears fruit with its seed in it.” (Genesis 1:11)
DINOSAURS
“Let the earth bring forth every kind of living creature: tame animals, crawling things, and every kind of wild animal. And so it happened. God made every kind of wild animal, every kind of tame animal, and every kind of thing that crawls on the ground.” (Genesis 1:24-25)
The logic here is simple. God created every kind of living creature. Dinosaurs were living creatures. Therefore, God created dinosaurs.
CAVEMEN
“God created mankind in his image; in the image of God he created them; male and female he created them.” (Genesis 1:27)
It stands to reason that God created man through the evolutionary process that included “cavemen” and led to modern humans.
The dinosaur argument also applies here. God created every kind of living creature. “Cavemen” such as neanderthals were living creatures. Therefore, God created them.
It is also worth noting that lower evolutionary forms of humans would not have the cognitive ability to understand or even conceive of God. This is why we have no record in Sacred Scripture of their interaction with Him.

So the dinosaurs fit on the boat thingy?

Hello, and thank you for your question. I will do my best to answer, but I will have to proceed from an assumption as I do not know exactly what you mean by “boat thingy.” I am assuming you are referring to Noah’s ark since it is, to the best of my knowledge, the only boat referred to in the Bible that is directly tied to animals. The apostles were fishermen, and their boat was mentioned, but there was no connection to creatures other than their catch of the day.
So, assuming you are asking if dinosaurs fit on Noah’s ark, I can confidently respond in the negative. There were no dinosaurs on Noah’s ark. Whether you believe the Noah story to be historically accurate, hyperbolic in nature, or a combination of the two (that’s where I stand on it), the answer is the same: no dinosaurs.
The source of the answer is simple–so simple, in fact, we need only look back to our elementary and high school education to find it. History, biology, and archeology tell us that man and dinosaurs did not coexist on earth. We were separated by millions of years. So, while Noah doubtlessly saw many birds believed by scientists to be decedents of dinosaurs, he would never have seen a dinosaur–just like neither you nor I have.
I hope this answers your question and I appreciate you giving me an opportunity to put a bit more thought into the topic.
God bless you.
