What was the energy source for the creation of the earth?

Answer 1

There are two answers for this question and both are theoretical. The first answer comes from religious dogma and is simply: God. This answer is infinitely more simple to give for the question, if not prove. Nearly every known religion on Earth accounts for the creation of Earth in the same way as it is written in the first verse of the Christian bible, "In the beginning God created the heavens and the earth."

The second answer to this question comes from scientific approach and has undergone an immeasurable amount of hypothesis, research, testing, and critical scrutiny over the years. Science tells us that, in the beginning, there was only a single super-massive gaseous point in our empty universe. Instantaneously and randomly, the gravitational bond holding this massive body together exploded and super-heated particles were projected outward through space, in a reaction called the "Big Bang". In less than one millionth of a second, protons, neutrons, electrons, and their anti-particles began to form as they traveled outward. As time passed, atoms were formed. These early atoms were joined together through gravitational force. The gravitational force of these early formations was so great that they collapsed in on themselves, and as hydrogen atoms bonded with one another, stars were formed through the reaction of fusion. Over millions of years, the fusion process completed its cycle for these early stars and they exploded, throwing out massive atoms into the universe. Over time, these atoms collected and combined to create planets, smaller stars, asteroids, and numerous other solid bodies.

As stars began to form in our galaxy, one appeared where our Sun now takes residence. After this first star burned through its usable hydrogen and other elements, it exploded, sending matter outward in all directions. Through gravitational forces, this matter cooled and collected in a few key locations, forming the planets in our solar system and the asteroid belt. While all of this was taking place, a smaller star began to form in the same location of the previous explosion and our Sun was born, starting its own fusion process.

The Earth was one of the planets formed from the collapse of the first star and it has taken billions of years to become the ideal home for life as we know it to be today.

Answer 2

The primary energy source for the creation of Earth was heat generated during the process of accretion, when smaller particles collided and merged to form the planet. This heat came from a combination of gravitational potential energy, radioactive decay of elements in the Earth, and residual heat from the formation of the solar system.
