Genesis doesn't mention the SNOWBALL EARTH either, or the LATE GREAT BOMBARDMENT.
Correct. Nor would I expect it to at a time before man could discern that such things had occurred - unless Genesis were authored by an author of the universe, which is the claim of believers. Remember where this began - with you showing how prescient scripture was by writing a list of four elements of the Genesis creation story that looked like something science might agree with. I pointed out that that list didn't resemble the scientific account of the evolution of the cosmos. It lacked universal expansion, inflation, and the formation of galaxies as part of my argument. You've added two more things not present in the account. These are evidence that the author of those stories only knew what was knowable at the time as the atheists suspects.
Genesis isn't a text book
It's the ancient equivalent, before there were textbooks, public schools, and universities. Like them, the scrolls were formalized instructional sources used to teach generation after generation what the elders deemed an essential education, which at that time wouldn't have been much more than religious instruction.
It is also said that the Genesis is not science, and the answer is the same. It's what preceded science before there was science, and attempted to perform the same function - explain how the world got to be the way it is. Before there was a method for studying the world, people just guessed how it got to be the way it is. Dozens or hundreds of creation myths were generated by an equal number of cultures, all of them guesses based on essentially no understanding of the world, and all of them far from the modern scientific account for obvious reasons.
Was it this thread in which there was a discussion of ancient morality as depicted in the Old Testament, New Testament, and modernity? The apologists were toggling back and forth between naturalistic and supernaturalistic explanations. At times we were told that God's moral truths are perfect, absolute, and timeless, and at other times, when moral failings of the past such as the practice of slavery were brought up, we heard about how that was another time with different circumstances.
You're doing something similar here by at once holding up this account as evidence of divine revelation and then explaining its shortcomings with comments such as it's not a textbook. The skeptic assumes that it is the work of men alone, and expects the pre-science to be wrong, and the older morals to be less evolved. The believer seems to like to borrow from that thinking when the human fingerprints in the teaching are revealed - 'that was then, this is now' - but then toggles back to this idea that the book is filled with timeless truths that transcend human ability and reveal a deity.
How do YOU know there is no transcendence or meaning to life? Where is your rebuttal?
There is transcendence and meaning to life, but as far as we know, not in the supernatural sense you mean. Self-actualization is personal transcendence, a kind of pulling oneself up by the bootstraps and exceeding one's former self. And meaning comes from within.
Incidentally, in the process of critical thinking, both arguments and bare claims can be rebutted, but the rebuttal to a bare claim can be as simple as there being no evidentiary support for the claim and therefore no reason to believe it. It's essentially a non sequitur fallacy in the sense that the claim is not supported by what preceded it, in the case of a bare claim, nothing. It's not a sound conclusion. That's the whole rebuttal, and its the same one for every bare claim. When an flawed argument is presented, a custom rebuttal is required, one that addresses the argument being rebutted, but not with bare claims. You've no doubt seen Hitchens' Razor, a pithy embodiment of that position: "That which can be asserted without evidence, can be dismissed without evidence."
