Why are you making an exception for a bunch of cells on a petri dish? Because a fertilized egg has the potential of becoming a human being?
I don't care what the Bible says. This is the vilest book I have ever read. You can safely dismiss EVERYTHING the Bible says.
A fertilized egg is not a human being. If you think it is, show me? Does it have a brain and liver? How about the lungs?
There is no exception. A skin cell is not a unique human with the potential for independent life. With a little time and support the human embryo will not only unfold into all of the secondary characteristics you so value it will also eventually learn to stand on its own and support itself.
Clearly you should care about what the Bible says perhaps then you would not be so keen to
sacrifice the most vulnerable human lives upon the alter of science.
You can play with words all you want.
The bottom line is that fertilized eggs will not become a human being without a human female host and a long gestation period.
When you throw away fertilized eggs you are not killing humans like you are suggesting. Those are just human cells like some spit on the side of the road.
Grow up. You live in some carefully constructed bubble. Even if you play with hundreds, thousands or even millions of human cells, you are still way short of the 37.2 trillion that the average human being has.
