The argument for "human life beginning at conception" is indefensible and ignorant of our knowledge of human biology and physiology. The reasons for this are quite simple: why draw the line at conception? Why not say that human life began several billion years ago and has continued since via a chain of organisms? The reason for saying a "human starts" at conception is based upon the silly notion that humans have souls that enter the child at conception. I suppose it communicates via the pineal gland like Descartes said?
But let's digress to another point completely; you think that a fertilized egg is special in some way, and that your god cares what happens to it. Explain to me, then, why less than 25% of the time, (on any given cycle) when a woman is TRYING to conceive, she succeeds, not because an egg isn't released, fertilized, and viable, but because it did not implant into the uterine lining. Then, of those, 25% miscarry by the sixth week. Of those remaining (down to 20% of the original ones trying to get pregnant) an additional 10% of them end in clinical miscarriages. So we're down to 18% chance of pregnancy with NO form of contraception and the woman is fertile, healthy, and on a good diet. To top it off, an additional 1% of births are stillborn.
So now let's review, if a fertilized egg is a newborn child, the ramifications for this are MUCH farther than you expected.
1) we must try and convict your god of murder
2) we must try and convict every woman to have ever had a child, because, statistically speaking, she's killed at least 3 for every child she's had.
3) we must engage in actively thwarting your gods plan to kill more embryos by removing the ovaries of all women and producing children for society by means of an artificial womb.
4) we must put your god in prison for a life sentence for each murder he/she/it committed.
Or we could just admit how silly calling a anything with absolutely no means of experiencing the world as we do "human." After all, humans care for humans out of empathy, but we cannot possibly conclude that an embryo suffers pain, feels joy, or has any thoughts at all, because thoughts require neurons, neurons are cells, and the most a birth control pill will stop is a few hundred undifferentiated cells.
Think he's gonna post it? Nah, I don't think so either.
