Some people say the dinosaurs were killed by the flood.
And if there was no flood there is a good chance that the earth had some kind of cataclysm that destroyed most of life on earth in the past 10,000 years.
Because history, recorded history, man writing and creating the wheel and leaving a record started within the last 10,000 years in Sumeria. There is no recorded history before that everything else is congecture.
The world Almanac of 1988 a non religious book stated on the first page that history began in Sumeria about 8,000 bce. That is when civilization began and man began writing and recording.
150 years ago man did not even know about Sumeria.
Some people say the earth is millions of years old and the dinosaurs died in a cataclysm as the ice age caused maybe several different ways.
I dont know, the earth could be that old. But I have read a lot about dinosuars being alive even today, and flying bird dinosaurs have been observed. And there are many storys in Europe about dragons being slain in midevil times.
I suspect if there were dinosuars alive in the dark ages, man would have killed them off. They would have killed a big dinosaur that would either eat men or provide food for men. They would kill them to extinction just as they have so many species today. Like the american bufalo.
I am not saying man killed all of the dinosaurs off, the cataclysm that inspired the flood story killed the greater number of them off.
Those who survived found an earth less hospitable to them and had to deal with men killing them off.
If you want to see some dinosuars that have survived come to Florida, We have aligators all over the place. They are dinosuars if you want to believe in evolution and an old earth they evolved from the triassic period 245 million years ago. Also we have little dinosaurs lizzards all over down here.
The best I can tell you there was a disaster that inspired the flood story about 8000 years ago. And some things survived and some didnt and they were killing dragons in Europe during the dark ages and we got dinosuars in florida today.
We have Sharks down here also, they are dinosaurs.
