who said Adam and EVE had belly buttons?
Do you have a belly button? Are you man that is descended from those made in gods image?
Do you have scars? Adam and Eve (if genesis was real) likely did not have belly buttons. The belly button is effectively a scar left from the process of being raised in a womb.
You're quite right adam wouldn't have needed a belly button, the point is that we do have one and have therefore deviated from the initial design.
You could equally ask why men have nipples if they were created specifically to be male.
Adam shouldn't have had them either as his fetus wouldn't have developed them until the Y chromosome kicked in. Or any of the other signs that males started female.
Yeah it's a facetious argument but it is evidence that the grand design was at least tweaked if it was real in the first place.
This leads on to may other questions about why the big man changed his mind.
Of course god could have given the belly buttons or not I mean the dude created them from dirt and spare body parts. If he wanted to he could have poked his finger in the clay and formed a belly button:) But there was absolutely no need or proof they had belly buttons.
lets take cloning and rasing a clone in a tank. perhaps the scientist who finally do this will decide that introducing nutrients through the belly button is not most effective way to feed a clone and then they will be born without belly buttons.
Yes, if it were a more efficient way then this could be possible. The fact is though since adam and eve, who is effectively adams clone, all humans have had "stuff" that wouldn't be needed by humans who were poofed into existence.
