Midrash Tehillim 90:13 says that God created and destroyed 974 worlds before this one. What exactly does that mean?
I've heard it used in defense of a modern understanding of evolution and cosmology but don't really get why God would create a universe and destroy it 600 times, then create a universe and destroy it a couple hundred more times with our solar system, and then create it and destroy it another couple hundred times with slight variations of animal life. And then do the one final creation of everything again. I don't grasp the logic behind that interpretation.
So what exactly does it mean to create and destroy 974 worlds?
