How could there not have been?
Because just like there was never just one fish and that fish turned into all the fish we see today, there was not one human. Many pre humans crawled out of the sea and started breathing air. Then we were small mammals while the dinosaurs ruled. Then we were apes. Then we were humaniods.
Doesn't it tell you anything that Chinese people developed their own unique language that has no ties to English? It wasn't like one person invented speech and then all the different nationalities put their spin on it. Asian people invented their own unique language. Just like they invented their own religions. Just like native American indians invented their own language and concepts of god.
It wasn't one person who came up with god or with language. That's because different tribes all around the planet evolved separately. We all started in Africa but eventually the one super continent broke up. The tribes that came out of the ocean in the west went one day, got lighter skin, etc. The Eskemos were probably north Africa and they trifted north, etc.
This happened over millions of years probably.
Was the one original dog? Or two? One female and one male? I guess if you take the Noah story literally you would say yes.
“Now, if the book of Genesis is an allegory, then sin is an allegory, the Fall is an allegory and the need for a Savior is an allegory – but if we are all descendants of an allegory, where does that leave us? It destroys the foundation of all Christian doctrine—it destroys the foundation of the gospel.” - Ken Ham
