You assume I am not?
Your previous comment, "Glad to know you worship the god Science." strongly implies that you hold science and the scientific method in contempt. So, of course I concluded that you are not fond of science.
And as I asked, and you refused to answer, what being intrudes the womb at 3 weeks gestation to implant the nervous system?
I am not good at answering nonsensical questions.
No, it doesn't, not in the least. "Worship" is not a synonym of "fondness."

Nothing nonsensical about it. You explained the lack of distinctly human characteristics in the fetus before week 3, because it lacks a nervous system. I asked who put it there, at week 3.
Seems easy enough to answer.
