if there were no God to create the universe, there could be no universe. Therefore if there were no God, there could be no science
If there's no God who eternally exists, how can existence begin? If there's no God who has existence by his own nature and doesn't get it from any cause, how can the gift of existence be passed down the chain of creatures, who borrow it from each other? If nobody has a certain book, how can others borrow it? If nobody has the authority to give a soldier a weekend pass, how can he ever get it? You can't give what you don't have. So somebody must have existence and not just borrow it.
It's from observing that everything dies, or ceases to exist. Now if there were no God who never died, who never ceased to exist, then eventually everything would die and nothing could begin again. And then there would be nothing at all. But that's absurd. There is something.
Well, the universe has more design in it than a house. How could it have happened just by chance? You know, there were two scientists talking to each other as the first moon rocket took off back in the '60s. One was a believer and the other was an atheist. The believer said, "Isn't it wonderful that our rocket is going to hit the moon by chance?" The atheist replied, "What do you mean, by chance? We put billions of hours of planning into that rocket." "Well, if you don't explain the rocket by chance, why do you explain the universe by chance? It's much more complicated than our rocket. We can design a rocket, but we can't design a universe." The same two scientists were walking past an antique store, and the atheist, who was an art collector, saw a painting in the window that attracted him. "Who painted that?" he asked. "Nobody", said the believer. "It just happened by chance."
