Discussion Who/What were we BEFORE we were born?

The original quote is, "we are made of star stuff."
- Carl Sagan, Cosmos

In a sense, we do come from stars. The elements that make up our bodies, such as carbon, oxygen, nitrogen, phosphorus, sulfur and iron, were formed in the cores of stars through nuclear fusion (nuclear-synthesis). When these stars went supernovae, they scattered these elements which over time coalesced to form new stars, planets, and eventually, life. So, most of the building blocks of our bodies were indeed forged in stars.
However, the hydrogen in our bodies is not of stellar origin. Most of the hydrogen in the universe, including that in our bodies, was created during the Big Bang.

The bow gives life by ending life for another. Life itself supports life by ending life for another. (This is fundamentally true down to the laws of physics. Entropy is always increasing. In order to live, we consume and compete for energy. Carnivores eat herbivores. Herbivores eat photosynthesizers. Photosynthesizers eat energy from dying stars. Stars eat energy from disappearing atoms.)
This is a reference to Heraclitus, a Greek philosopher who is known for his belief that the nature of the universe is composed of the shifting balance between opposites. "Logos."

This is really opening my mind and helping me to understand life and death and the universe better. I really enjoy reading your responses. They are always so informative and so interesting. Thank you.

Edit: I started watching, Wisdom of Carl Sagan - Cosmos, and I can't stop watching it!
