everything is created intelegently by the christian god
now i can see you saying why are there so many poison plants.
and i say to that god cursed the ground when Adam ate the forbidden fruit
Then to Adam He said, "Because you have listened to the voice of your wife, and have eaten from the tree about which I commanded you, saying, 'You shall not eat from it'; Cursed is the ground because of you; In toil you shall eat of it All the days of your life. "Both thorns and thistles it shall grow for you; And you shall eat the plants of the field; (Genesis 3:17-18)
