I'm not blaming anything on God. It's these creationists who are calling Him a liar -- who needs to trick his people by making the world look older than it is.
God is not trying to *trick* anyone with the appearance of age. It could simply be a matter of mere practicality. In order for the earth to be useful to man, it would need to be in that condition. Much as if I wanted to provide my house for company to use. I would have it built to start with, finished, and furnished. I would even go as far as stocking the pantry and perhaps leaving leftovers in the fridge so they could just reheat dinner. There could be all the signs of having been lived in and yet that would be untrue. There certainly would have been someone there to do all the work but it wasn't *lived* in even though it would have appeared that way. But it would have all been for the convenience of my guests out of courtesy not decietfulness.
Creationists are doing no such thing, calling God a liar.
