But this clearly is not in the Biblic
This is not what Genesis teaches, Humans and Animals(Dinosaurs) inlcuded came into existence on the same day(6th day). No life ever came or existed outside God. The earth was desolate. Desolate means that its state was lifeless like other Mercury or Jupiter.
The Bible does not teach that the dinosaurs pre existed before humans. They all came into exstence during the Creation Days.
Humanity could have easily survived the dinosaurs by picking out mountain tops and hill tops that were difficult for dinosaurs to climb or reach for survival or islands that dinosaurs wouldnt reach for fear of drowning..
Well, with what we know about dinosaurs, especially the meat eaters, mankind could not exist along side them. Not only that, they would not be included with reference to the common animals. And if they were animals, why are they not mentioned when God had them male and female for the ark? I would submit the following translations as well:
King James Bible
And God blessed them, and God said unto them, Be fruitful, and multiply, and
replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth.
American Standard Version
And God blessed them: and God said unto them, Be fruitful, and multiply, and
replenish the earth, and subdue it; and have dominion over the fish of the sea, and over the birds of the heavens, and over every living thing that moveth upon the earth.
English Revised Version
And God blessed them: and God said unto them, Be fruitful, and multiply, and
replenish the earth, and subdue it; and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth.
JPS Tanakh 1917
And God blessed them; and God said unto them: 'Be fruitful, and multiply, and
replenish the earth, and subdue it; and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that creepeth upon the earth.'
==========================================
I've noticed that there are several translations which say "replenish" the earth, which means to 'fill something up again, to renew.' Now I am not proclaiming that this is the case, but am just putting it out there. If the word replenish is correct, then it would mean that something was on the earth prior to our creation. If you're replenishing something, it means that it was previously plenished/filled. That being the case, then what if the dinosaurs were on the earth at an earlier time, before this current creation. Again, I am just speculating, putting this out there. Obviously mankind could not co-exist with dinosaurs anymore that he could co-exist with the offspring of the angels who took wives, who were 300 cubits tall and who Enoch says began to devour men and which is the main reason why God brought the flood.
Nothing set in stone, but Just food for thought
