Believing in creationism is a sin

[Esquilax]

Of course it extends to other things, the difference between us is that I understand which they are, and you do not. :p

How could it be sinful before God told the Israelites? That would be nonsensical.

Don't you believers usually advocate some kind of objective morality? How can it be objective if it changes based on the words of some creator?

Beyond that, can you envision a case in which you would find murder to be morally alright, even if you had never been told it was by god?
