Imagine believing that every speck of energy that comprises the universe suddenly came into existence without any cause or explanation.
Imagine believing that 13.8 billion years ago, also without any cause or explanation, all of this matter suddenly exploded outward, governed solely by the laws of physics which had somehow come into existence, again without any cause or explanation.
Imagine demanding that people who don’t believe that the universe is causeless and meaningless must use logic (the laws of which apparently came to exist, once more, without any cause or explanation) to prove that the universe had a Creator.
Now imagine being provided with logical proof that the universe has a Creator and saying, “That can’t be true because sometimes children get cancer.”
These are the people who think that the Creationist’s views are irrational.
