I must say that I find the line of thought behind your question obscure. Do you suppose you could explain what you have in mind? If the copulation of your parents (or great-great-great-grandparents) is to be regarded in the same context and scale as the explosions of the stars that produced the metals that constitute your substance, then why the emphasis on the copulation without which you would not have been here? After all, you also would not be here today if you had not been here yesterday; in a very real sense you come from yesterday, and a good deal more nearly immediately than from a little copulation nine months or a great deal more  ninety generations before you were born.

Do please try to clarify what it is that you are asking. Science can tell you a great deal, but only if you ask meaningful questions. If on the other hand you do in fact know of some source that can tell you the answer to meaningless questions as well, do please tell us, because I doubt that anyone among us would know that.

Cheers,

Jon
