Life exists in sperm cells and it exists in egg cells. It exists in spores and it exists in pollen. It exists in the heart removed from a recently dead person and in any other organ from a recently dead person and it continues to exist in the person who recieves that organ and nourishes it within their body and subsequently lives a full and productive life after having received this gift.

Life is everywhere.

That is not the question of interest here, though.
