These flashes are produced in the presence of sperm enzyme, not sperm. A now human life is not being created, so it is not the soul. I think God wants us to go on faith rather than scientific knowledge for spiritual questions, in which case He may have chosen not to allow us to see the soul enter a new human life. That doesn't make the soul any less real. It just makes it a question outside the scope of science.

How do you know the enzyme isn’t what produces life?
Scientists are frustrated——THEY CANNOT QUANTIFY GOD.
