You know...it is funny. I used to not believe anything in the Bible...but as I grow older, I see the trends reflected very strikingly. SO I have recently started considering the following:
Have you ever played a video game where they had books that gave you information you would need to win? The books are a kind of guide. Well what if something/someone ensured a book like this was made for our world? What if we are, in fact, in a very very realistic "virtual reality" scenario? Wouldn't it be entirely possible that the books of the Bible (and other similar religious texts) were placed here for the same reasons?
Big stuff. All I care about is having control over my life.
That Religions / religious texts can contain things which are wise and seem very relevant to our lives, does not imply that they must have been inserted into our reality by some entity outside of it, whether a divine creator, or a programmer of a simulation. After all, if they were created by humans as a collection of the wisdom of those humans, they will contain some things that seem to be 'good morals', 'wisdom about human experiences', 'how we should treat each other', etc, because humans will have recorded the things they learned about how a society should work and how its people should interact. Of course, they might not agree with everything our culture now believes about human morality, since our society changes and evolves, and it might decide things such as "slavery is evil" and "you should genocide other races" and "homosexuality doesnt hurt anyone, you should let people life and love the way they want".
Examining the evidence it seems very likely to me that these holy books reflect the cultural beliefs of the humans that lived when they were written. For example, we all believe very strongly now that slavery is evil. We all think "if there were a divine creator who was supremely good, certainly this being would also think slavery is evil!". Thus, we should predict that if the ancient holy books were written by such a Divine creator, they would say slavery was evil. When we observe them, we see that the really old ones support and accept slavery. So our observation supports the hypothesis "they were written by the humans that lived at those ancient times".
If you want to now make a hypothesis "our universe is a simulation created by some beings, and holy books are put into the simulation by those being for X purpose", then here are some more things to consider:
This hypothesis considers that these books were inserted into the simulation, but how was that achieved?
If the simulaiton started at the big bang, and ever since then everything in the universe has evolved according to the laws of physics, then how were things inserted into it? Also, why are the things being modified in the simulation such complex structures? That is, consider that the laws of physics determine the laws of chemistry, which then determine biology, which then determine how a human brain works. Are beings outside the universe really making modifications to the computaiton of the universe as it is running? Is the idea of outside beings 'hacking' the universe's state at such a high level at all realistic? If the universe is hackable in this way, like a computer programmer inserting a breakpoint in a program, and going in and changing the value of a variable, then why are we unable to find any evidence of this occurring? Why do all our observations seem to follow physical laws?
If the simulation began much more recently, such as during human history, with an initial state that included these holy books, then why was this point chosen? If the creators of the simulation chose to interfere in such a way, then clearly humans are very important, so why did they make so many different stars, in so many different galaxies, in so many different galactic clusters, and have the simulation provide computation for all of this universe, if the part here on earth is the important part?
If the creators of the simulation started it at such as initial point, how would they have made its past history so internally consistent? That is, why does it look to all our measurements like the universe began at the big bang point, and passed through almost 14 billion years of computation to arrive at the present state? If it had been created at an initial state thousands of years ago, how could everything about that state have been so carefully constructed that it appears to provide a clean history of how that state evolved over time, through the laws of physics, in such a completely consistent way?
I guess I could continue on, but I should just stop and post a link to some wirting that could do a much better job than I could, and suggest that everyone should go read this:http://www.amazon.com/Rationality-AI-Zombies-Eliezer-Yudkowsky-ebook/dp/B00ULP6EW2/ref=sr_1_1?ie=UTF8&qid=1430434666&sr=8-1&keywords=rationality%3A+ai+to+zombies
