  1. CONSIDER THE FOLLOWING: GOOGLE SEARCH: (4/17/2023): 1. Where did all the water on Earth come from? Multiple geochemical studies have concluded that asteroids are most likely the primary source of Earth's water. Carbonaceous chondrites–which are a subclass of the oldest meteorites in the Solar System–have isotopic levels most similar to ocean water. 2. How much water is on the Earth? The volume of all water would be about 332.5 million cubic miles (mi3), or 1,386 million cubic kilometers (km3). A cubic mile of water equals more than 1.1 trillion gallons. A cubic kilometer of water equals about 264 billion gallons (1 trillion liters). 3. How many asteroids have ever reached Earth? Based on crater formation rates determined from the Earth's closest celestial partner, the Moon, astrogeologists have determined that during the last 600 million years, the Earth has been struck by 60 objects of a diameter of 5 km (3 mi) or more. 4. How much water is in an average asteroid? A cubic meter of asteroid dust may have as much as 20 liters of water. 5. What is 1,386 million cubic kilometers divided by 20 liters? (1386 million (cubic kilometers)) / (20 liters) = 6.93 × 10 to the power of 19 6. That is a lot of asteroids with water in them. And what about all the other planets and their moons in our solar system that have water on them? Evidence points to oceans on other planets and moons, even within our own solar system. But Earth is the only known planet (or moon) to have consistent, stable bodies of liquid water on its surface. In our solar system, Earth orbits around the sun in an area called the habitable zone. 7. Where did all the oxygen that makes up water on this Earth come from? The answer is tiny organisms known as cyanobacteria, or blue-green algae. These microbes conduct photosynthesis: using sunshine, water and carbon dioxide to produce carbohydrates and, yes, oxygen. * Note: Water and Carbon Dioxide already contain oxygen. Producing oxygen from oxygen. Yea, I don't think so Google. You didn't say how oxygen came to this Earth in the first place. (Water: H2O ; Carbon Dioxide: CO2 , both already contain oxygen). 8. Where does oxygen in the universe come from? Carbon and oxygen were not created in the Big Bang, but rather much later in stars. All of the carbon and oxygen in all living things are made in the nuclear fusion reactors that we call stars. The early stars are massive and short-lived. They consume their hydrogen, helium and lithium and produce heavier elements. * Note: The singular big bang is most probably a fairy tale for various reasons. 9. Do stars periodically nova? Among novae that are closest to Earth, the cloud of expanding debris can sometimes be seen in telescopes a few years after the explosion. A nova can flare up repeatedly although there is not a fixed interval between outbursts. Of the 200 billion stars in our galaxy, 30 to 50 explode as novae each year.

  2. OXYGEN: (copy and paste from my files): a. Supposedly oxygen is generated in the core of stars, at temperatures around 100 million degrees 'C' through a process of fusion of lower elements. b. The Sun is supposedly made up of mostly plasma (electrons disassociated from atoms). c. Water on Earth of course is H2O (2 Hydrogen atoms and 1 Oxygen atom). Hydrogen is the most abundant element in this universe. There is a lot of water on this Earth. So, 1. How exactly did the oxygen from the center of stars get to this Earth? 2. And if oxygen can get from the center of stars to this Earth, where is all the oxygen on other planets and moons? (Of which they should have Hydrogen atoms on them, so where is all their water and oxygen molecules?) d. And what about all the other oxygen atoms that make up other oxygen molecules on this Earth? They all had to have come from stars as well. How exactly did the Earth get flooded with so many oxygen atoms? Periodic novas of our Sun? (And nitrogen atoms and some other chemical elements in those novas too that reached this Earth?) e. 'IF SO', then when is the next Sun's periodic nova? And what of 'life' on this Earth? 1 side of Earth blasted the other side away from the Sun okay? And what if we have species in outer space, on the Moon and/or Mars and the Sun novas?
