I generally think with the belief that once you come to the realisation that god - or the christian god, who I was brought up to believe in - is just as likely as any other spectral or spiritual life-guiding being, you can believe in whatever you want, because they are just as likely to be true. Unless, of course, you're a believer in the "small gods - American gods" theory, in which case, meh. I'd hang out with Mr Wednesday.
So, basically, the idea of a god on a computer is as plausible as the thought of a god with a quiver full of lightning bolts. No matter what you believe in, you will probably go to the same afterlife.
So - if you have the belief in NO god, and instead believe in an afterlife where your thoughts and personalies are electronically sent through to a different reality or universe, where you exist as a spectral form made up of only the memory of what you were before, then it's possibly the same Ideals. As they say, nothing dies, it is just changed. Therefore, when you lose the unknown 26 grams upon death (I think that's the exact amount.) it could be you losing your "soul", or, the digital imprints that were once ingrained upon the cells of your brain, and are moved to be ingrained upon something else.
And therefore, if you believe in a god which can take your digital imprints, and use them to place inside a host of electronics, then your beliefs - that you are a human, that you have brown hair - could cause your simulated identity to manifest - leading to heaven, or, the recycle bin. So it's entirely possible that we are an incredibly intelligent AI simulation program that has been made in order to learn and evolve for a purpose, or for entertainment. When you think about it, with the invention of Spore, we currently have the capability to make things evolve while in a computer - if we were to input a variety of "codes" like natural selection and such, perhaps they would grow to eventually be the advanced civilisation we are today, which connects through the internet to post on a forum, when there is millions of billions of people stored on a single centimeter squared of computer space.
Screws with your mind, dunnit?
Woah. That's the second most wordy Theological speech I've made in my life. Also, I'm an agnostic and a Steevist.
