If stars are really well over 6000 light years away, how could light have had time to travel from them to Earth?
Two logically possible answers have serious problems:
God created the starlight on its way: this suffers grievously from the fact that starlight also carries information about distant cosmic events. The created-in-transit theory means that the information would be ‘phony’, recording events which never happened, hence deceptive.
The distances are deceptive: but despite some anomalies in redshift/distance correlations (see Galaxy-Quasar ‘Connection’ Defies Explanation), it’s just not possible for all stars and galaxies to be within a 6000-light-year radius—we would all fry!
But if light were billions of times faster at the beginning, and slowed down in transit, there would be no more problem.
