In order to believe the world is 6,000 years old, then you have to believe that God created it then with all the evidence to support it looking as if it's 4.5 billion years old, including burying fossils of creatures that never actually existed.
And he created the stars that we can see that are 13 million light years away at the same time.
He did this, apparently, to fake us out.
I was actually told once that it was Satan that planted all that silly old earth evidence to fool us and lead us away from God. So I guess the jury is still out as to whether God planted the evidence to fake us out or Satan did it to lead us astray.
