Ask AI: When does science say human life begins?

The question of when human life begins is more philosophical and ethical than it is scientific. Scientifically, fertilization is the point at which a new, genetically distinct human organism begins to exist on a biological level. However, people have differing opinions based on personal, religious, ethical and philosophical beliefs about when a fertilized egg or embryo becomes a human “life” in terms of having personhood or rights. Therefore, different people interpret the onset of "human life" at different stages of development such as conception, at a certain stage of fetal development, or at birth.

The answer to this question is still a subject of scientific and philosophical debate. Some argue that it begins at conception, while others argue that it begins at the moment of birth or at some other point during the pregnancy. Others argue that it doesn't begin until the person reaches a certain level of neurological development. Ultimately, the answer to this question depends on the specific beliefs and values of the individual.
