I can admit there's grey area around "where life begins", but it certainly isn't at "conception".

Oh really?

Human Embryology by William J. Larsen, 3rd edition, 2001
“In this text, we begin our description of the developing human with the formation and differentiation of the male and female sex cells or gametes, which will unite at fertilization to initiate the embryonic development of a new individual” (p. 1)

“After the oocyte finishes meiosis, the paternal and maternal chromosomes come together, resulting in the formation of a zygote containing a single diploid nucleus. Embryonic development is considered to begin at this point. The newly formed embryo undergoes a series of cells divisions called cleavage as it travels down the oviduct toward the uterus. The cleavage divisions subdivide the zygote first into two cells, then into four, then into eight, and so on.” (p. 1-3)

Langman's Medical Embryology, T. W. Sadler, 7th edition. Baltimore: Williams & Wilkins 1995

"The development of a human begins with fertilization, a process by which the spermatozoon from the male and the oocyte from the female unite to give rise to a new organism, the zygote." (p. 3)

The Developing Human Being by Keith Moore and T.V.N. Persaud, 7th edition, 2003

"Human development is a continuous process that begins when an oocyte (ovum) from a female is fertilized by a sperm (spermatozoon) from a male. Cell division, cell migration, programmed cell death, differentiation, growth, and cell rearrangement transform the fertilized oocyte, a highly specialized, totipotent cell – a zygote – into a multicellular human being.

I have a ton more citations that say you're full of shite, would you like me to go on? Why do you deny science?

BTW, I am a biologist, how about you?
