Moderators cleaned up four answers on the Was the Earth one big ocean once? question after leaving a few days to the authors for fixing.
While these answers were interesting and sometimes highly upvoted, they did not conform to the standards required on this site and have been removed according to policy.
I'm opening this meta question to provide context, document the reasons for deletion and allow community discussion.
If you are one of the authors and want to fix your answer: do so and then flag; we will reopen answers which are fixed.
fredsbend's answer only referenced the top answer as a valid source. It also had a link to an answer on Christianity, but it was about what waters mean in Genesis. Neither the original, nor the current version of the question referred to the Genesis at all. He made it clear he suspected that part was off topic: "the theological aspect of the question [...] may be off topic here". However simply removing that part would have just left a link to the top answer.
Bart's answer was a theoretical answer about how the Noah's ark story does not make sense. The theory presented is that disproving Noah's ark means that the Earth was not covered by oceans. This would be on topic if the question was about the ark, but unfortunately the question has always been about the oceans. Neither the original, nor the current version of the question referred to the feasibility of Noah's ark at all.
David Culp's answer relied on the "snowball Earth" hypothesis. This would have been a great answer, albeit a bit of a stretch, if that hypothesis was backed by evidence. Unfortunately, as the author also mentioned in the answer ,"this theory is unproven".
LCIII's answer was about the Genesis again. It is repeating the claim without giving evidence, as it did not have any reference.
