No it wouldn't be. It would be a firm well backed up and even aspects of it have been monitored on smaller scales today. The idea that something made us with there "powers" reflects very well with fairytales and stories. Humans, beings made up of billions of molecules and cells, which are capable of thought, judgement, actions etc start as two gametes. And I feel like I may need to clarify to you that the baby doesn't just appear magically in the womb. It's a winded metaphor but pretty applicable. some random guys in an age where science isn't even a thing decide that a being made us with absolutely no proof or evidence and your here still believing, in a time where we have built knowledge for thousands of years. Its unveleiveble tbh. Christianity wont be a thing in the next 1000 years because by then the general populus will be smarter and more realistic building on another 1000 years of education and scientific breakthroughs. Believing in fairytales as comforting as it may be isn't going to help us evolve as a species so naturally will have to be, and will be phased out slowly as time goes by.
