What difference does it make when God created the universe--10,000 years ago or 10,000,000,000 years ago

It makes a HUGE difference. Who do you believe when He created the universe, some scientist or The Creator?

And what difference does it make how God created life--spoken word or natural forces?

It makes a HUGE difference. One either believes The Word of God or they don't. If one doesn't believe The Ever Living, All Righteous. Almighty God when He said He spoke the Universe into existence, then they do not follow His teachings and, therefore, is not a Christian. They can 'claim' to be Christian but it doesn't make them one. They discount His Word for their 'own truths'; self-righteousness, pride - saying they know more than The Creator.

Being a Christian doesn't mean believing there is a God, it means believing IN HIM and His Living Word and following His teachings.

Accept the fact that the Bible isn't written directly by God, otherwise it would be "In the beginning I created the heavens and the earth."

You shouldn't claim it is when it's obvious it is not.
