So there really is a fetal god? Isn't it superstitious to explain this with science?

Hello, no! Buddhism talks about the laws and principles of the development of all things.

Although science is very advanced, we haven't found the real truth yet. It's too common now. Science is a double-edged sword: computers and networks were invented, and then there was an addiction to the network; Drugs and vaccines are getting newer and newer, but viruses are also beginning to evolve ... Science cannot solve all human problems, especially mental problems.

Therefore, the law of scientific discovery can be said to be only the skin of Buddhism. I suggest that if you want to know more, you can look at Buddhist philosophy more.
