Do you

God knew, but it's like, if you had a child, and although they were very good somtimes, but they could also be very bad, would they NOT have the child? Most parents would have the child anyway. And I think that is how God is. He knew what we would do to the planet, but He loved us anyway to go ahead and make it. I also believe He has provided us with of ways of fixing some of the planet's problems.

If he knew that and still made this wonderful place he doesn't deserve to treated as a God. He would be more foolish than the dumbest mortal living here. If he didn't knew that we would mess up the planet then he would be more ignorant than the most ignorant person living in this world. So God would appear either dumb or ignorant but never both.Regards

He knew that it was possible. after all he did give us free will.

i think after adam and eve(eva) ate the apple..from that moment ..he knew for sure where we ware(are) going to go to
