Well, look at this one for example, in the bible, it states homosexuality is a sin, however it says nothing about viewing images of homosexual practices as being a sin, so those who wrote the bible, didn't fathom this as a possibility.
There are some believe, that god is in control of everything, that he's allowed science and technology to advance to allow such things to exist, that our will to create, is controlled by god's grand design. However I don't believe this to be the case, if god didn't want to be surprised by what we as a human race can create, have created, and will create, then humans wouldn't be instilled with free will.
