Yes, life begins at Conception. By your two questions in the prior posts, I think you believe the contrary? For me, it's against my religion to think any other way. The Scientific embryonic articles explain why it's a life at Conception.

When Does a Human Become a Person? -- by Francis J. Beckwith, Ph.D. Continuing the previous essay, Dr. Beckwith demonstrates why other functional criteria given for personhood--such as sentience, brain development, and viability--are inadequate. He then refutes the "gradualist" position, which incorrectly asserts that the unborn becomes more and more human as the pregnancy progresses. Finally, he discusses the positions of various abortion and infanticide advocates like James Rachels, Mary Wollenkott, and Michael Tooley.

Does Life Begin At Implantation? -- by Francis J. Beckwith, Ph.D. In this essay, Dr. Beckwith addresses the phenomena of monozygotic twinning, hydatiform moles, choriocarcinoma, blighted ova, cloning, and fertilization wastage. He then shows how these phenomena fail to disprove the position that human life begins at conception.
