Attn: Theists - What would it take to prove you wrong?

[Sword of Christ]

The atheist/naturalist view seemed far less likely when we had a more limited understanding of our universe.

A little bit of science will take you away from God but a lot of science will bring you closer to him. Once you understand everything that was involved in a creation of the universe such as this and ultimately humanity is becomes very difficult to see it in terms of a blind natural force.

The farther back you go and the more limited the understanding, the less likely it seemed.

The Bible if you read what it says about the universe and Gods relationship to it, though it gets a number scientific details of the universes construction wrong (they thought the Earth was flat and stood on pillars), still stands up to scrutiny today. You will it powerfully moving to read.

The more we learn and understand about our universe, the more likely it seems. The reverse seems true for religious claims and belief systems. It may not be long before your latter statement is amended to remove the "very." And perhaps not much longer before we remove the "un" from "unlikely" as well.

I already went through the atheist stage in my mid teens to mid 20s so I've given it a decent go. If you want to get properly serious about your atheism have a read of Lucretius On the Nature of Things, it sums up your view of the universe very nicely. The Satanic Bible by Anton Lavey while it may be some kind of deism is also good satire of religion from the naturalists perspective and The Grand Design by Stephen Hawkings will give you a few pointers of what a purely material/natural universe would in practice involve.

You can read On the Nature of Things online, it's as close as a thing as you can get to an atheist religion text, though he would have seen it as a religion in itself not a lack of one.
