Is a zygote the first step in the life cycle of every sexually reproducing organism?

I keep hearing from embryologists, medical doctors, and biologists that a zygote is the initial stage of life for a sexually reproductive organism. What do you guys think?

  • Zygote is the initial stage of life.
    Vote A
  • Life begins after birth. (Please explain what birth is for non-gestating organisms)
    Vote B

  • The zygote is when an egg meets a sperm. Life does begin after birth, but also before it. There are specific criteria for what defines a living organism, and a zygote is the earliest form that can be defined as a living organism.
