Not saying my brother is wrong, but want to give a counter to this.
if God made the earth and heavens to support life on earth, which was created on day 6, Then God would have created the stars to appear on day 6 on earth no matter how many light years away they are
so the earth and solar system would have an appearance of age, it would have to to support life.
If God can create man and all life, plus the universe and set it so perfectly to support life, he can create it aged enough and ready to support that life at the time he created it.
He has no need of creating things fast and making them look old.
Billions of years are nothing to Him.
