That's what it is all about.
I know, I was an atheist for almost 16 years.
Atheism is for people who can't face reality. Not the other way around. Atheists are the most religious people you will ever meet. The problem is their religion is ridiculous and their "god" sucks and can't deliver. Time to get a new God.
The more you know about the real world, the more you realize it is no accident. The world is beautiful. It is the humans who make it ugly. Without the wicked clouding the frame you'd see it in technicolor.
They are determined to make certain it ends badly. They can't take the beauty that might result otherwise.
What's the alternative to their rocky primordial world of flesh eating cold blooded monsters? A lush garden of Eden that was filled with beautiful birds as big as houses who ate mainly plants. I would still recommend avoiding the beach because of Leviathan but otherwise I reckon you'd find you could source lunch in the Jurassic with a lot less work than you do now to get it.
I was talking to somebody the other day who pointed out that the Bible knew there was a thirty block shark swimming around in the ancient oceans before anybody else did. In fact, it speaks with such authority on the beast you would think it is an eyewitness account. Impossible, of course - unless everything you know is largely wrong. For example, did the Earth really have more oxygen back then ... or was it simply plants and trees were much, much bigger than anybody alive today might be willing to believe? Big trees that generated more oxygen in one day than all the plant life in the modern era can produce in a year?
