The stardust drifted thru space until gravity coalesced it into a whirling mass that became our sun and its planets. The energy from the sun - sunlight - is what feeds us and animates us. The food we eat is built of stardust and photosynthesis, the photosynthesis of course being run by sunlight.
Interestingly enough, the stardust and the sunlight have a common origin: Gravity. Gravity is what makes a star in the first place, drawing together the Hydrogen and other elements into a sphere and compressing the sphere until its nuclear fusion engine ignites. It's the force of gravity that generates the pressure that presses two positively charged protons (Hydrogen nuclei) together with enough force to cause them to fuse into Helium, releasing energy that we call starlight/sunlight. It's gravity, that when Hydrogen is depleted, makes a supermassive star continue to fuse even heavier elements like Carbon, Oxygen, Neon, Sodium, Magnesium and so on, until its core turns to Iron. At this point, atoms (even subatomic particles) are packed in so closely that fusion no longer releases energy into the star. It is now solely supported by electron degeneracy pressure -- the quantum mechanical law that prohibits two electrons from occupying the same quantum state.
When the core is massive enough, even electron degeneracy won't support the star and it collapses. Protons and electrons in the core merge, releasing a tremendous amount of energy and neutrinos. This, in turn, powers a shockwave that tears through the star ejecting its remains violently into space as it totally explodes into a supernova, the force of the explosion making even more elements as well as scattering the resulting stardust out into space where gravity can eventually pull it together again to make a new star and its planets.
It seems that heaven and earth were created by Gravity. But wait - that's supposed to have been the doing of God! Could it be that Gravity and God are the same? Let's check this out:
Of course Gravity doesn't run a gated community called Heaven. Gravity doesn't listen to prayers (let alone answer them!). And Gravity doesn't have any kids to send here to save you. Your salvation/liberation is a do-it-yourself project. Luckily clear instructions have been provided by previous Gravity generated beings. But remember, all the things created by Gravity are subject to decay; you better diligently work on your liberation. Best wishes for success in that project.
