Science!

WHY can a woman become pregnant and another human is growing inside her?
Where did that supposed mass that preceded the earth come from? What is ITS origin?
How could that mass of whatever breakaway and then this globe of rock there became water...then something crawled out of the water...then over ,million of years we have the human body with 78 amazing organs. Then we eventually have women who can get pregnant? Who or what is the great scientist who made all this possible?
WHY is everything but God something some people want to grasp on to?
I'm willing to entertain that proposition. But before I grasp onto God as the most likely explanation, I'd like to ask:

Why is God the only plausible (or even most likely?) explanation?
Where did God come from? What is HIS origin?
How did he manifest the creation(s) of our world/galaxy/universe? And is he still doing it, or was it a "once & done" type of thing?
Who or What created "the creator"? Was it a "big bang" of some sort, or are we to assume that God has always existed, despite never having been created?

Not trying to be a smart aleck here....asking sincere questions. I believe folks see the solution they WANT to see. As you can see(?) from my questions, both perspectives have valid questions about underlying theories. JMO...

I don't want to debate religion either, as I believe it's a personal thing between an individual and their higher power. I can respect that. But my observation is that you question why others don't accept; but I wonder why you accept without question. You don't have to answer that....it's meant to be rhetorical. Alternative perspective....nothing more...
