Because They Really Don't Know

Glimpse at Early Universe Reveals Surprisingly Mature Galaxies: Observations challenge standing view of how and when galaxies formed.

"This was the most comprehensive survey ever done covering the bulk of the galaxies that represent conditions in the early universe," Glazebrook said. "We expected to find basically zero massive galaxies beyond about 9 billion years ago, because theoretical models predict that massive galaxies form last. Instead, we found highly developed galaxies that just shouldn't have been there, but are."

They'll figure out some other way the universe was created formed without God. They'll still be wrong.
