No, the eggs are fertilized outside the womb and kept in a fridge for a while. For a period of time, I existed as a viable embryo in a fridge. Then, I was thawed out and inserted into the womb. I was, human life, in a fridge for a while. Unless, you consider me when I was frozen as non-existent? I suppose that's possible. But I was certainly "thawed" out outside of the womb and kept outside the womb temporarily until the transfer took place. At that point did I exist?Which was then put in the womb, correct. You didn't grow in some petri dish but in your mother's womb.
