Is creation good now? Has it been good at any time since the Fall?
The creation waits in eager expectation for the sons of God to be revealed. For the creation was subjected to frustration, not by its own choice, but by the will of the one who subjected it, in hope that the creation itself will be liberated from its bondage to decay and brought into the glorious freedom of the children of God.
We know that the whole creation has been groaning as in the pains of childbirth right up to the present time.
Romans 8:19-22
This is good? Creation is good now? The MOMENT Adam and Eve sinned, creation stopped being good. Therefore their sin could not result in the knowledge of good and evil via the creation unless they already knew the good.
