Genesis 2:15 "The the Lord God took the man and put him into the garden of Eden to cultivate it and keep it."
it appears that some wish to focus on the fact that Adam and Eve tended the Garden of Eden and that this means they had the intelligence to comprehension God's commands ..so let's put this to rest by simply asking one question ..where there other animals in the Garden of Eden that could do the same thing as Adam and tend or maintain a Garden? ..well there is the leaf cutter ant
the left cutter ant have formed their own agricultural system and would go out in force and cut leaves from trees and transport these leaves into the nest in which they used the leaves to grow a type of fungus in which the colony would feed on ..
since this fungi was the ants only food source the ants would have to maintain it and would cultivate the soil remove waste and debris and would even built the nest in such a way to aerate it in order to keep the fungi at a steady growing temperature ...
so since these ants tend their Garden do this prove that these ants were intelligent enough to comprehend God's command not to cut leaves off the Tree of Knowledge ...
in other words as Adam and Eve was tending the garden of Eden these Ants was tending their Garden of Fungi which means Adam was doing nothing more than these leaf cutter ants were capable of doing ..but yet do any one believe that those leaf cutter ants could comprehend God's commands
also another point of focus is just because Adam named all the animals that this proves Adam's level of comprehension skills ...well let's use those Leaf cutter ants again.....
since ants communicate by leaving different chemical scents or signals then with every encounter with a different animal those ants could identify or name that animal with a special chemical scent ......
but the point is that Adam naming the animals was nothing more than a Leaf cutter ant naming an animal with a chemical scent...and because the ants was capable of doing this doesn't mean that they could also comprehend God's commands ..
