This happened long long ago. It's difficult to say the exact day in the BC or AD era.
All of us would want to have a feed back on what we have done. It could have been your stage performance or a painting or an article or a home maker's new dish at the dining table and so on.
In the same way, God Almighty too wanted to know right from the mouth of Adam and Eve of what they thought about their body design?
The Holy Bible says that God created Man in His own image. Won't "Own image" mean that all parts of our body are the same as God's? So, we can infer that God too has a head with eyes, nose, ears, two hands, two feet etc exactly like us.
In one of His usual daily afternoon visits, God happened to ask, "Adam, are you happy, my son? Is everything all right? Do all fruits get digested well?"
Adam didn't understand the meaning of the word 'digested'. So he gave an answer at a tangent "The pineapple pokes my tongue, Father God."
"Next time, peel off the poky skin and eat the inside. Okay/" God had advised.
Adam's eyes shone at the advice. Why didn't it occur to him earlier? He had remembered to cast away the banana skin, but as regards the pineapple..."
But this is not what God had wanted. So, He came straight to the point Himself. "Are you happy with two hands, two legs Adam?".
He thought over the point for a minute and said, "Father-God, please give me a tail like the monkeys..."
"Tail? What for, son?"
"Father God, when I feel scratchy at the back, Eve refuses to scrape me nicely. She just runs her palm over the surface and runs off. That's why?"
God turned His head Eve-wards with a jerk.
"Father-God, Adam wriggles and writhes when I touch his back. I think he feels tickled. He...he...he..."
Interrupting her, Adam said, "If I have a long tail I could scratch my back right up to the end all by myself until I feel satisfied. I don't have to depend on Eve, Father-God."
"Have you any suggestions in this regard, Eve?"
"Give him a tail and be done with it Father-God. But I don't need any tail. When I want my back rubbed, I go to a deer. He has long nice horns and he can scrub my back well and proper. But, one more thing Father-God.
"What is it, my child?"
"I would like an eye at the back of my head, so I can see who follows me. I could also rub my own back by manipulating my left arm and right arm, especially if Mr. Deer puts his price up! I don't want two eyes in front."
"Oh!" exclaimed God Almighty. He felt so pleased that Adam and Eve could think for themselves so logically, a characteristic that was absent in His other creation in Heaven, the angels, who were almost like robots receiving and executing the orders faithfully without argument.
But God was in no mood to alter anything that He had already given His human beings. "Supposing they ask for two pairs of hands and two heads! It may be difficult to convince them against sporting too many limbs and heads. They think pretty fast too....."
"That's all for today, children. See you tomorrow.." and God had disappeared for the day.
After God had taken leave of them, Adam took Eve to task. "Why did you ask for transfer of one eye from the front to the back.?" he demanded.
"Because I want to see what goes on at my back side. You too make fighting gestures standing behind me, don't you?"
"Yes, I try to frighten you. That's all. Did you like my bid for a tail?"
"No. You should have asked for two more legs so that you could run as fast as the cheetah."
Even now, I can outrun Mister Cheetah, " Adam asserted.
"No, you can't. You will lose. Mister Cheetah runs very fast, you know? Shall I arrange a contest, say tomorrow?"
"Okay, " Adam agreed and looked forward to the dawn of the next day.
