Accretion is impossible with a flat Earth, so I can't wait to see if anyone can up with another explanation. However, like 50 people have viewed this, yet only I have replied... Silence indicated the FE'ers have nothing.
The reason no one answers, is because there is no definitive answer...so whats the point? You can't answer the same question about a round earth. There is only faith, and theories on how the round earth was created. So for us to come in here and try to pin down a creation mechanism is just asinine.
Theories based on obserervable and thoroughly tested evidence, belief in these theories is not faith as faith is belief without proof or evidence. Just in case you choose to argue this:
faith (fth)
n.
1. Confident belief in the truth, value, or trustworthiness of a person, idea, or thing.
2. Belief that does not rest on logical proof or material evidence. See Synonyms at belief, trust.
3. Loyalty to a person or thing; allegiance: keeping faith with one's supporters.
4. often Faith Christianity The theological virtue defined as secure belief in God and a trusting acceptance of God's will.
5. The body of dogma of a religion: the Muslim faith.
6. A set of principles or beliefs.
Definition from the free dictionary.
Also the question concerning a creation mechanism for a flat earth is not asinine. RET has a working model which explains to a high degree of observable accuracy how the world came to be formed. FET has nothing to explain this (or pretty much anything else from what I can see), which means FET is less plausible than RET in terms of evidence.
