He meant that the elements that make you up were forged in stars and when stars go nova, or super nova, all these elements are spewed into the cosmos and constitute all matter, including living beings.

Because your body is made of whatever food you ate. All that food came from the earth. The earth is the broken down rocks of planet Earth. All the planets are chunks of stuff that stuck together and came from STARS.

All the elements heavier than hydrogen were made by fusion in a star. Sagan is saying that the atoms that make up our bodies were once a part of a star.

No, the SETI program (Search for Extra-Terrestrial Intelligence) program pre-dates Sagan, but he was a fervent promoter of it. If any one person could be said to have "invented" SETI, it would have been Frank Drake.

What is Carl Sagan's religion?

Sagan himself answered this, "I'm agnostic."; which simply means he does not know if there is a god or what the nature of god might be and does not believe that this is knowable.However admitting not knowing something does not prevent having an opinion on the subject and developing personal beliefs. For Sagan these personal beliefs leaned towards a form of pantheism comparable to Einstein's belief in Spinoza's God. His son, Dorion Sagan said, "My father believed in the God of Spinoza and Einstein."Therefore one could call Carl Sagan a pantheistic agnostic (i.e. an agnostic that has voluntarily chosen to believe in pantheism without requiring evidence for it).


What did Carl Sagan mean when he said you are all star stuff?

Simply that the atoms humans are made up of were forged in the furnaces of dying stars. The basic elements that make up a living body or cell were all created this way, all the elements that exist (with the exception of Hydrogen and Helium) were all created in the fireballs made up of the two elements mentioned earlier.


Why people are concidered as part of the universe?

We are considered part of the universe because you are in the universe, created in the universe and if science is correct everything that goes to make you comes from the universe. Every part of your body except the hydrogen was produced in a star. The Iron and sodium in your blood, the carbon in you, the oxygen you breathe were all created in the core of a star. Heavier elements such as iodine where produced in colossal exploding stars called supernovae. The famous physicist Carl Sagan once said "We are all star stuff". Even the hydrogen in you body was created in the Big Bang. Another quote from Carl Sagan. "We are a way for the universe to know itself." Similarly everything that makes anything you know is made up of parts of the universe. Carl Sagan said "If you want to make an apple pie. First you must create the universe."
