Yeah, but the bacterium doesn't develope into a human being.
That is the difference.
Why does it matter if something develops into a human being?
We also don't know that it will develop- it may be "rejected" by the mother before it develops, it may die on delivery, it might be born without a brain...

What makes something a "human life"?
Who decides what human lives are valued?
I can't help noticing that you have dodged my question.
I would say that a conscious, self aware being is intrinsically worth valuing highly- this would include the vast majority of adult humans, even the severely mentally ret*d, in fact most humans over the age of 2, as well as many species of primates, rodents, and other mammals (I would specifically pick out horses, dogs and pigs as likely to be self aware), and probably some non-mammalian species.
That doesn't mean that other animals aren't worth valuing- a recently fertilised embryo may be valuable because it means a lot to a human, likewise a goldfish. Spiders might be valuable because they kill flies or mosquitoes. You might say that the "low level" of consciousness enjoyed by a 3 month old child or a cow is also intrinsically worth valuing.
