I've noticed people who don't like evolution like to throw around "it's just a theory!"
Theory: A set of statements or principles devised to explain a group of facts or phenomena, especially one that has been repeatedly tested or is widely accepted and can be used to make predictions about natural phenomena.
There are a lot more facts supporting evolution than creationism. There are no facts supporting "the Earth is only 7000 years old".
Back to the original debate on ABC, the argument that God is infinite...if it is possible for God to exist, be infinite, to have no beginning and no end, without a creator, is it not possible that the same can be said for our physical universe?
Our universe has no beginning and no end. It has always existed, and it is infinite. It had no creator. If you can use that argument for God, we can use it for our universe.
