First off, I don't know my first "mum" and "dad".
Our "recorded" genealogy (on my father's side) only go back to the 28th generations.
On my mother's side, it is less well-documented, and my mum know of nothing before her great-grandparents.
We have no records beyond that, so anything I say about before these ancestors of mine, would merely be speculation.
Second, this topic you have started, only say about "your body", and not about Adam and Eve, or any other mythological ancestors.
So I am assuming you mean that is "my body" was created or designed.
So the answer would be the same as my first reply, as well as to all my known ancestors: created through reproductions.
We are certainly not made out of clay, as your Qur'an say.
The most basic molecule or compound of clay is that of clay minerals:
hydrous aluminum phyllosilicate
This mineral is formed when sediment rocks erode and decompose.
We do have trace elements of aluminum and silicon in our body, but not in this molecular form.
Our body has mostly the following elements: oxygen, carbon, hydrogen and nitrogen.
But in terms of the most basic molecules and compound, water is the highest. Other compound are protein, fat, carbohydrates, hydroxylapatite (it's what make up bones), and DNA.
Less than 0.01 percent (to be more precise, 0.0058% or 0.001 kg) of silicon are found in the adult human. The presence of aluminum is even smaller than that (0.000015% or 0.00006 kg). With that in mind, there are not enough silicon and aluminum to make clay. And neither of these two atoms are essentials to life...not unless you are a plant.
So how can we possibly be made out of clay?
