There is absolutely nothing in the entire universe, no event in all of history, no natural law you can point to and say, "This is proof there is no God."
We as creationists fail if we agreed with the false premise that you can have life without the creator or the system of designs that contained it. We would deny our world view which would make us nonbelievers. Thats silly.The counter-statement to intelligent design is not "God does not exist." It's, "Divine creation or guidance is not required to explain the development of life as we observe it." It is possible to prove that second statement, and unnecessary to prove (or make) the first one.
And who cares?
