Does Life Begin at Birth?

The thing about Oh-Blah-Blah that scares me the most is his ambivalence about when human life begins. Estase believes that it starts at conception, but many abortion supporters consider birth as the start of a child's life. Oh-Blah-Blah claims ethicists (Peter Singer???) are undecided on when life begins. When is that point Barack? Is it two weeks after birth? Is it two months after birth? Is it when a child enters Kindergarten? This is really scary.
