1 cell is certainly a person, just a very young one. Part of the human experience is being 1 cell at one time. You are not 1 cell for very long, but it’s absolutely living and growing, and part of the human condition. Life has many stages, and humans are complex creatures, and takes us time to develop into our full form. Everyday there are over 300,000 humans around the world that are one cell, and over 100,000,000 in the womb. These are all humans, just young ones that look and act different than you and me. In only a few months they will grow and develop to look more “people like”, but they are still people. Denying them their humanity is anti-scientific and immoral, imo.
