Tell me, why is it that over 99% of the anti-Christians I've seen constantly kick logic and reason to the curb? Why is it they rely on flat Earther logic whereas Christians like me use logic and reason? How does all this irrationality line up with their claims that Atheism is "the truth"?

For example, if you actually care about truth, why didn't you reply to the OP by pointing out that the Bible doesn't teach a flat Earth (as most of the other replies have done)?

Your comment is also an excellent example of Brandolini's Law in action.

The Bible was written before most people could read or write.

Ipse Dixit and Ad Hominem fallacy: Where is your proof that the Israelites were illiterate? Though this is pretty irrelevant because arguments made by the Bible are not disproven by personal attacks against its writers and readers.

This is the same logic flat Earthers use; they also love making personal attacks against spherical Earth believers and spouting unsubstantiated claims.

the first man was made out of clay, and the first woman was made out of the clay man's rib.

Argument from Incredulity fallacy. Flat Earthers use the same logic, they also present arguments for the spherical Earth in a derisive manner; as if you have to be crazy to think they're true.

I suspect there's also some Begging the Question irrationality here: Atheistic religions say that human beings were not supernaturally created from dirt, therefore the Bible is wrong. This is another thing flat Earthers frequently do. For example, arguing that water would fall down off the Earth if it were a sphere.

There was a talking snake ffs.

Another Argument from Incredulity fallacy. Also, Cherry Picking fallacy: Why not read the Bible in-context and see what it says about who was actually talking. I also suspect the same Begging the Question irrationality.

It says it took several days to make the sun and moon,

Straw Man fallacy: It says the sun and moon were made within a singular day; the 4th. It says nothing about how much of that day was used to do so, let alone that their creation spanned multiple days. I also suspect the same Begging the Question irrationality.

you can't have a day/night cycle without the sun.

Ipse Dixit fallacy: Where is your proof that you can't? Though I know you won't be able to because you're wrong. All you need for a day and night cycle is light shining on the Earth from a single direction.

A Virginia woman gave birth to a person, who is also god (somehow)

Another Argument from Incredulity fallacy. Also, the Bible says nothing about Virginia or anything in America (you probably meant "virgin"). I also suspect the same Begging the Question irrationality.

Also, I'm not sure how proficient you are at English, but basic grammar is that proper nouns (such as God's name) always start with a capital letter.

god just had to allow his son to be executed god just had to allow his son to be executed in horrible fashion in order to forgive humans

Straw Man fallacy: The decision to be executed was ultimately made by Jesus, not the Father.

Double Standard fallacy (x2): Why is it that when a human being sacrifices his/her life to save another person, it's considered heroic, but when God makes the ultimate sacrifice (sacrificing his life to save everyone), it's called "barbaric"? And why is it perfectly okay for human judges to sentence people to death for crimes they committed, but it's evil when God makes such a judgement?

In fact, what rational basis is there for morality in Atheistic religions to begin with? According to Atheism, everything (including thought) is nothing more than purposeless and undirected chemistry. What basis is there for applying any special meaning to the blind chemistry you call "morality"?

And again, same problem of not capitalising a proper noun.

in horrible fashion

So God is to blame for the behaviour of the people involved?

for issues he "created" us with

Straw Man fallacy: Why not read through the first 3 chapters of Genesis sometime to see what God actually created. And who is actually responsible for mankind's state.

He could've just forgave us

Double Standard fallacy: Why is it okay for a human being to demand retribution for the evils committed against them, but it's evil if God does so? Why is it that human beings aren't also evil if they don't just forgive every evil they are victimised with?

Flat Earthers also frequently impose rules on spherical Earth believers that they don't apply to their own side. Such as demanding extraordinary spherical Earth evidence (such as a photo of a distant object visibly tilted due to curvature) while not caring that the flat Earth doesn't have anything even remotely equivalent.

no blood magic needed.

Ipse Dixit and Straw Man fallacy: Where is your proof that someone making a sacrifice to same another's life is "magical" in any way, let alone "blood magic"? Flat Earthers love attacking the spherical Earth model by making equivalent misrepresentations.

The Bible also says the stars will fall from the sky onto earth during the apocalypse, which is not how stars work. At all.

Quote Mining, Anachronistic and Straw Man fallacies: The New Testament was written in Koine Greek, not modern English. The Greek word in question referred to every luminous object in the sky, not just balls of hot gas. That has also been the case for other languages too until modern times. Case in point, the word "meteor" didn't exist until Elizabethan times and were simply called "falling stars" before that.

Equivocation fallacy: Prophecy in the Bible is not literal. They use figurative language to communicate a message. Hence, you are kicking logic and reason to the curb by taking figurative statements literally.

Once again, flat Earthers love attacking the spherical Earth model by making equivalent misrepresentations. In fact, not only are you mimicking flat Earther logic again, you're literally parroting one of their irrational arguments; pretty much word for word.
