Life begins when all of the elements (egg, sperm, uterus, and so forth) are provided to a biological entity that will enable it to grow and/or maintain existence. If you take away even one of these things, life is impossible, and the entity will die because life cannot be sustained.

Life begins when all of the elements (egg, sperm, uterus, and so forth) are provided to a biological entity that will enable it to grow and/or maintain existence. If you take away even one of these things, life is impossible, and the entity will die because life cannot be sustained.

Die: (from Dictionary.com) to cease to live; undergo the complete and permanent cessation of all vital functions; become dead.

If life must be sustained, there must still be life. The words of your argument belie its incorrectness.
