"I did n't mention that the physical entity needs nothing but nourishment , oxygen , and a safe environment to be able to grow into an adult human being , but that is also a statement of fact that can not be reasonably disputed ."
"Actually , it can . The zygote does n't always develop into an adult human being . In fact , about 60-70 % of all zygotes never implants or gets rejected and end up being flushed down the toilet . And of those who do implant , some turn into blighted ovums or hydatidiform moles . So no , your claim is not as all-encompassing as you want to present it . [ quote ] Conception/fertilization is the time in which this physical entity comes into existence . Prior to that time , this unique physical entity did not exist . [ quote ] Which is also true after ANY cell division of any kind , and as such again is a rather meaningless point ."
