My favorite source for evidence related to science these days is the Discovery Institute. Not only do they employ the rock star of science and religion, Dr. Stephen C. Meyer, but they have a bunch more excellent speakers. They publish a lot of books, and many of those are made into audio book versions. One of the guys I like the most is Brian Miller, who contributes to their books and does videos.

He did a recent video talking about the Big Bang cosmology, and its relevance to the question of God’s existence. It’s important for people who prefer the young-Earth interpretation of Genesis to realize that the Big Bang is not compatible with naturalism. It’s actually lethal to naturalism, because it requires a SUPER-natural cause to bring the natural world into being. I have friends who prefer the young Earth interpretation of Genesis who argue with the co-workers and family members from the Big Bang, just to get them started on their spiritual journey.

Anyway, here is the video:

And here are the questions that he answers:

• What is the big bang theory?
• Why did scientists initially dispute the big bang?
• What did scientists believe before the big bang?
• What models have been proposed to maintain the idea of an eternal universe?
• Why did scientists come to accept the big bang?
• Who is Georges Lemaitre?
• How did the scientific community receive Lemaitre’s idea?
• How did Edwin Hubble contribute to the big bang theory?
• What is the most compelling evidence for the big bang?
• What does the big bang imply about belief in God?
• Are there current critics of the big bang model?
• Why is an eternal universe so important to atheists?
• Why is the big bang theory still being challenged?
• Did the universe have a beginning?
• What are the arguments against a beginning to the universe?
• What is a singularity?
• Does the universe need a creator?
• What about the idea of a multiverse?
• Lawrence Krauss thinks the universe possibly came from “nothing.” How would you respond?
• What does Lawrence Krauss mean by nothing?

If this is something that you have not looked into, this video is a pretty good primer. He only mentions the expanding universe and the cosmic microwave background radiation as evidences. But there are other good ones, such as the light element abundance predictions (75% hydrogen, 24% helium) and the second law of thermodynamics (entropy) that he could have mentioned.

There are definitely open problems with the Big Bang cosmology, but the main thing that Christians should know is that this evidence is used in formal academic debates by people like William Lane Craig, Stephen C. Meyer, etc. to annihilate atheism. Personally, I would be thrilled if the scientific evidence tilted towards a young Earth. And it very well could, and there are good people working on that problem. But I do think that all Christians should at least be aware that the current “best” cosmological model is lethal to atheism.
