^^^ You think it's fucking reasonable to believe that we're stuck to the surface of a spinning ball in a vacuum orbiting a million-mile wide thermonuclear bomb in an endless virtually empty universe created by nothing exploding for no reason?
The only way anybody could possibly believe any of that shit is if they were indoctrinated and brainwashed from birth.
Occam's Razor, the universe as a quantum fluctuation, that at some point in 10^10^10^10 years, however, there is no time before the universe, so the concept of this is rather meaningless. That the right quantum fluctuation created an explosion so large known as the big bang. The asymmetry between anti-matter and matter, "The LHCb data revealed a significant level of asymmetries in those CP-violation-sensitive quantities for the Λb0and Λb0-bar baryon decays, with differences in some cases as large as 20%." as in regards to the Large Hadron Collider. However the preliminary findings are level of 3.3 standard deviations, so about 99.9%+ usually it warrants a 5 standard deviation.
Explains why the result isn't 1-1 or a total of 0, but something other than 0. Hence you get stars, galaxies. Billions of years and trillions of planets to conduct random mixing paves the way for the chance of life. And a documentary shows that mixing a bunch of elements together in a certain fashion and environment can arrive at a pre-state for life. Do this a trillion-trillion times, it becomes much more likely that one time results in the needed outcome for life. From 100 billion possible places on a single planet to 100 billion in a galaxy, to 100 billion galaxies in the universe. So you got 10^11*10^11*10^11, or 10^33 as in 1,000,000,000,000,000,000,000,000,000,000,000 Possible attempts at achieving life.
From there, replication, and variation paves the way to life, and evolution to us. A single-thing as pre-cell replicates a billion times, say 99.9999% dies, you are left with 1000, which are just different enough in variation to survive, and they copy themselves. Some are losing the ability to copy, and others maintaining it, over time, you get variation and change. Where some change and variation is better than others. These better variations take over and continue, ones that find consuming another within their cluster as an energy source is an more optimal method, paves for more complex versions, of them running away from each other, and a form of competition, speed, and shape (Survival of the fittest). Which continues and cointunes, perhaps in size, and cooperation is more optimal, which paves the way to the first simple organisms.
Size, is more optimal, which keeps going on for 100s of millions of years, as it takes a loooooong time to get anywhere. You get simple sex-tiny things and a form of cooperation, in a way to life. Paves to larger, and larger, then eventually fish like life. Life can tend to want to spread around, so one that escaped and went on to land, at a start had that advantage, that the one in the sea didn't. These again, competition, speed, shape, form, eventually intelligence to plan against another became an advantage. To simple creatures, to mammals, to larger faster. Upright, cooperation, and eventually early humans, humans, civilization, and us today.
*I skipped like 99.999999% in between here, but basically the concept.
To say that we are existing in a beginning state of the universe a magical super being, that created this dome around a flat planet, is starting from a top-down approach saying that God created everything. And why specifically this super-being created Flat Earth only and nothing else? Why not square earth, Cube Earth, alternate dimension, etc? Why a complicated metallic dome holographic around a flat plane? And nothing else? And why is your concept right, and no others is?
When bottom-up, from a single point, skipping the need for the convenience and explanation of how everything works. So out of nowhere, this so-called being popped into existence said "Hey" I want to create flat earth, with a dome around it, and it will be populated by a 5 pointed intelligent organism, 1 head, 2 arms, 2 legs, for the lols.
It's the same as if you threw 50 coins on a table at once, and expected all of them to land on the side. It will tend to result in the simplest most common approach. You are the one that is brained washed with all this nonsense.
