Кто убил Адама и Еву? Бог или сатана?

Who killed Adam and Eve? God or Satan? The Bible describes the history of man’s sin-fall. And at first glance, it seems that Adam and Eve made the wrong choice. Therefore, they are the ones responsible for their death. But why was the tree of knowledge of good and evil in the center of the Garden of Eden? Why was the tree beautiful, and the fruit hidden for the eyes? Why did God allow Satan to visit Eden? Why did God not create this tree on the edge of Eden, in the most inaccessible place, and make the fruits unattractive? And why, did God allow Lucifer to tempt men?
