Carl Sagan once said that "Extraordinary claims require extraordinary evidence." You know what? We agree! Though not in the way an atheist might think -- if it could be said that an atheist thinks. The burden of proof is more on an atheist to show there is no creator than it is on a Christian to prove that there is. Why? Because all human beings inherently understand design.
This is referred to as Empirical Adequacy. Pick any object and you inherently know it was created. But no atheist will ever be able to refer to anything coming into existence without cause or creator. Even if he were to cook up some example of random processes, he runs into the Implied Creator Paradox, because he had had to create an example of non-creation.
The statement made earlier about how atheists don't think? We aren't trying to be derogatory. We're simply following their logic. If we're nothing but the result of accidental process, than human beings are just walking sacks of chemicals. And chemicals cannot reason. They only react.
And that's a pretty good description of some atheists.
Romans 1:19-21, "For what can be known about God is plain to them, because God has shown it to them. For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse. For although they knew God, they did not honor Him as God or give thanks to Him, but they became futile in their thinking, and their foolish hearts were darkened."
There's no reason to have to prove God's existence because everyone inherently knows God is real and His word is true. All of the evidence is already there when we understand the text.
