It should be clear to anyone that believes in the bible, that the earth is both 4.5 billion years old and 6000 or whatever number of years old.
When God made Adam he made him as an adult. If you built a time machine and went back to 10 seconds after his creation you would think he was 20 or whatever number of years old not 10 second old. The earth was made in the same way newly created but looking old.
Free men own guns, slaves don't.
