We are all parasites period, whether we are in the womb or the entire human race. We are parasites on the earth and you can tell that by the way we treat this planet. You seem to think that this little planet can hold infinite amounts of people, it cannot especially the way we treat it. If you want to save the children of this world I recommend starting with the planet you live on.
In your original diatribe you used the words ‘I think’ which are your personal beliefs. The word belief does not necessarily mean God. You also made a statement that 'There is an official scientific definition of LIFE.' Hmmm I call Bullshit on that too.
“The definition of life is controversial. The current definition is that organisms maintain homeostasis, are composed of cells, undergo metabolism, can grow, adapt to their environment, respond to stimuli, and reproduce. However, many other biological definitions have been proposed, and there are some borderline cases, such as viruses. Throughout history, there have been many attempts to define what is meant by "life" and many theories on the properties and emergence of living things, such as materialism, the belief that everything is made out of matter and that life is merely a complex form of it; hylomorphism, the belief that all things are a combination of matter and form, and the form of a living thing is its soul; spontaneous generation, the belief that life repeatedly emerges from non-life; and vitalism, a now largely discredited hypothesis that living organisms possess a "life force" or "vital spark". Modern definitions are more complex, with input from a diversity of scientific disciplines. Biophysicists have proposed many definitions based on chemical systems; there are also some living systems theories, such as the Gaia hypothesis, the idea that the Earth itself is alive. Another theory is that life is the property of ecological systems, and yet another is elaborated in complex systems biology, a branch or subfield of mathematical biology. Abiogenesis describes the natural process of life arising from non-living matter, such as simple organic compounds. Properties common to all organisms include the need for certain core chemical elements to sustain biochemical functions.” Wikipedia see I can look stuff up too
So even in the scientific community there is room for disagreement.
