Answer 1

Older than was thought possible does not necessarily mean older than the universe. The most likely answer is we were wrong about how early galaxies can start forming. But that’s what science does, it tests and tests and tests and when something despite all our tests still can’t be proven wrong that is usually the accepted fact. But accepted is the key word because the testing never stops.
