Can you imagine when the universe was not yet in existence? When it was suspended in imaginary time.
If you think about how things come to be and the myriad of miraculous coincidences that have propelled or rather brought us to where we are now.
The fact that I can write this blog post. The fact that I can apply my cognitive reasoning. The fact that the atoms on my laptop are holding up with the strength of its bonds and not disintegrating. The fact that the moon is high in the sky and regulating the earth's waves.
And then I think about us. About our meat vessels, about our consciousness and witness-consciousness and how at our core, we are but a highly complex system of atomic systems. How at essence, we are integrating as a system of atomic systems with other atomic systems. How we must leave energy residues and parts of ourselves with everything that we interact with.
Our lives and all we hold dear are miraculous coincidences. Let us begin at the beginning or rather the point of non-being.
Imagine all (or rather the lack of all) before the "Big Bang", when all that was to be was suspended in imaginary time.
And then the universe expanded out into time and space as a hot, glowing fireball and rapidly cooled while it expanded. Protogalaxies contracted and began to break into fragments. Gravity then caused the fragments to contract even more and to become very hot as they compressed. Nuclear fusion then began within their cores.
Our solar system begins its birth dance as the cloud of interstellar gas and dust condenses. As the cloud collapsed, a dense, slowly rotating core was formed. This would become the sun.
Our nascent earth experienced numerous collisions with asteroids. This produced so much energy that our earth formed a molten core that was composed mostly of iron. the lighter elements then floated to the surface and created our rocky mantle. Our early earth's surface was molten, it had no solid surface.
The atmosphere consisted mainly of nitrogen and carbon dioxide. photosynthesizing bacteria were not present as of yet. We had no oceans either. Most of the water that is present on the earth;s surface was released from the mantle in volcanic eruptions and had come originally from collisions with comets ("dirty ice balls").
Our surface cooled enough for the oceans to form and created a hospitable environment. Amino acids, on the tails of comets that brushed the earth's atmosphere, blessed us with the building blocks from which proteins are formed.
Amino acids and the other organic chemicals were present in the primordial oceans only in small quantities. Darwin suggested a highly likely warm pond where chemical evolution took place. RNA (the primitive form of DNA) then could form. The first living organisms were primitive algae and bacteria.
It then took 3 billion years for multicellular life forms to evolve on earth.
