thanks for that it is excellent .Here’s a few facts…
There's no scientific definition of "clump of cells" that means anything other than: a living organism made of cells.
At fertilisation, a new and distinct human DNA sequence exists; one that has never existed before and will never exist again.
At 6 weeks, there's a heartbeat.
At 8 weeks, fingers.
At 10 weeks, the ability to feel touch.
At 14 weeks, a baby rubbing tired eyes
The "clump of cells" argument isn't an argument at all.
