4. Humans come from eggs & sperm, not soil chemicals?
1. If they are not eaten, they contribute to the "circle of life" by seeding, withering and dying and once more becoming part of the soil.
2. It doesn't "turn into an animal" it is absorbed by the animal and is used as fuel or protein for growth or is jettisoned as waste.
3. They don't contribute to evolution, but they do contribute to the "circle of life." A burnt body gives up its water and its oxygen to the atmosphere (plants "breathe in" carbon dioxide and "breathe out" oxygen. Solid products (ash) find their way (eventually) back into the earth.
4. We are what we eat. The food we eat (whether meat or veg) comes originally from the earth in the form of plants. A foetus gets its nourishment from its mother via the placenta. Once it is born it initially gets its food from its mother's breast. Once weaned it eats food which down the line originates from the earth. Our bodies are made up from the nourishment we put into them (including the sperm and the egg). When we die, our bodies decay (or are cremated) and find their way back to the earth so that the cycle/circle of life continues.
