I don't recall having said the earth is not 4.5 billion years old. Perhaps I wasn't clear or you misunderstood.
The second verse of Genesis in most texts say, "the earth was without form and void..." The Hebrew texts can be translated as, "the earth became without form and void..." There are several other verses that indicate that the original earth was destroyed by a cataclysmic event. The upshot is that the original earth that God created, the one He created before it became without form and void could well have been 4.5 billion years old.
That's what is commonly thought, but it's not accurate. Actually, the book claims it was written by men who were inspired by God. Also, the scriptures are not religion. Religion is man made, the scriptures are God inspired. Huge difference.
Even if the Bible is a fairy tale, at least one should know the fairy tale before talking about it. It is usually clear when I'm talking with someone who might know the tradition, but they know little of what it actually says. Not to be critical, but I believe you fall into that category. There is nothing wrong with not knowing. The problem comes when someone thinks they know when the facts show they really don't. Most already know what it says before the even crack the book open. Not very scientific.
All humans today, born from sperm and an ovary, the same as parents, grand parents, great grand parents. About the length of a life observing self in a natural human history to quantify, God did not invent me.
Theism, just talking, as a human already living, owning a human life, pretending.
For did science, human owned/expressed inventor of his own designed inventions on scientific intent, to design, build, operate use to convert more Earth mass ever be in reality anything else?
The answer is a direct no. Yet you say I will discuss gravity. Yet you personally did not own inventing gravity, you pretend in groups to discuss information for egotism.
For natural is a status, space, empty, space irradiated not empty, space with cold gases in them or cold mass form. Just a general observed reality.
As a human being a human, conscious of self, human with other humans.
Discussing any topic or want of a discussion by your human say so.
Science was invented by humans for invention only, its owned origins. For surely you cannot believe that you talk about huge massive bodies in space as if you own them by giving them a word and a name description from a human want?
Natural is a self observed quoted basic scientific advice. You live on a planet inside of an atmosphere with other life forms, on a planet and can invent.
You cannot invent unless you think first for a design and the matter for design is abstracted off the body of a planet. Your science invention does not come from anywhere else...but the planet mass. Then you take more mass from off the planet and change it to get energy.
You create change in science.
Now if science talks gravity yet says a huge spatial body, unknown to their mind about how big it is...owns all the bodies sitting in it. And then you make a theme about one condition that does not exist in reality. For gravity does not exist by itself....all bodies of discussion are space, empty space, heated irradiating space, gases hot and cold. What status does science as a human personally own?
Just your own self as a human.
Sophism was qualified to be described as a contrivance using words.
Who applies the measure? A human scientist does.
A human has never lived on Planet Earth as God stone philosophy when it was without form and void, one of your owned teachings. A human scientist had to propose God not existing to own a thesis for how to react to get energy in human reality.
