What if we assumed to replace the earth by our universe? Or, if you insist, the earth was "a part" of the universe. So the description of the universe also applied to the earth.
Except the Earth
did not exist at that time. The Earth didn't form until around 4.5 billion years ago, from heavier elements that had been cooking in stars for a few billion years.
Look, this creation myth makes perfect sense when you just read it simply, and accept that it was a primitive myth penned by a primitive people. Then it's obvious what it's saying: they believed that the Earth, Sun, Moon, and a few thousand stars made up the entire universe. They believed that the Earth was of primary importance among these, and so had it created first. Only later were the other objects created.
But it makes no sense whatsoever when you compare it against the history of the universe. Sure, you can take a sentence here or a phrase there out of context and see how it kinda sorta sounds like it might be talking about something that actually happened. But once you look at the context, it's immediately clear that it is talking about something else entirely.
For example, when God said, "let there be light," the context makes it quite clear that the text is talking about simple illumination. By contrast, when the early universe first became dominated by radiation, the temperature would have been well in excess of ten quadrillion Kelvin (10^16 K). No simple illumination this, but a temperature the likes of which hasn't been seen since, a temperature hot enough to cause the nuclei of atoms to evaporate.
Furthermore, the text is talking about light specifically, but the energy at that time would have been distributed across a broad range of standard model particles, such as quarks, electrons, muons, gluons, and others. The actual energy in photons would have been quite small compared to these others, but we call it "radiation dominated" because as far as how they effect the expansion of the universe, they would have acted at those high temperatures just like photons act.
I am not dumber than you. But I started to consider Christianity in my 25 years old. Thirty years passed, I am still learning.
Oh, I'm still learning too. I just don't think theology has anything of interest to offer me, so until they can actually present evidence, I see no reason to bother learning more in this particular area. I will naturally continue to pick up odds and ends here just due to discussions, but I see no reason to actively spend my time learning more when there is no reason to believe that any of it is of relevance to reality. My time is much better spent learning things relevant to my life and my work.
That is fine. Then stop using humiliating words.
I have no idea what you're talking about.
