That lie is as old as the Genesis story. It sifts down to saying that God must be responsible for Evil else it would not exist in the Universe He has created. You are a dead soul, a liar, and a servant of the father of dead souls ... and that is not God The Father Almighty.
And still you cannot define what consciousness actually is or how it comes to be in the gestating new human being, or even a gestating dog. Your mind is so twisted in worship of your little god science that you are unable to think clearly. And your continuing lie over the developing embryo, claiming it is an undifferentiated mass of cells until well after implantation, even as that new life seeks implantation to support its will to live, is evidence of your bankrupt soul. There are three distinct levels to human consciousness, but since you do not discuss philosophical issues, we can assume you would not read or acknowledge them if offered for your contemplation, so bye bye, enjoy your 'science driven life' as you lie your way into eternity. Wouldn't want to be you ...
Oh, goodness.
It seems I forgot a “not” in there—if God did *not* want people like me to exist (...) we wouldn’t exist. And saying so is not presuming to speak for God—since God is the all-powerful creator of the universe, we can conclude that everything that exists in the universe is by His will. Thus, I am exactly the way God wanted me to be.
I guess you are unaware of the enormous body of work that has taken place in the field of neurobiology, demonstrating quite clearly how the brain functions. Shall I start linking to some of the imaging studies that map brain activity and show where specific kinds of thoughts occur? And which demonstrate that brain activity changes in specific ways in different consciousness states? If there is any group of cells in which such activity can occur within the pre- or even early post-implantation embryo, there would be some sort of imagery or study that demonstrates it. But the only thing that comes close, to my knowledge, is the observation that the neural tube starts to fold in week 3—the time that all of the organs and tissues start to differentiate.
The burden of proof that a clump of cells can be consciously aware of anything really is on you. The only reason I can think of for pushing a definition of human being that does not include actual human form and function is to provide a rationale to condemn women for using contraceptives. I’ve already said that no amount of childish name calling or insults (aka bullying) will change my opinion on that. I simply will not condemn contraceptive use. And I won’t start elevating every single cell or clump of cells to human being status, just because it could be induced into developing into an embryo through the application of the proper mixture of biochemicals.
