It appears the quote was truncated, probably by accident. Following the link (a 2 stage process due to the URL having been changed at some time in the past) I have got the full post. It says:
"Any of You folks ever heard this theory?
If so, what do you think-
The Earth used to have another layer around the biosphere which was mostly moisture(most anthropoligists agree the earth used to stay at a constant temperature-this may help explain why...) , and a passing planet with an elliptical orbit to our own destroyed it, causing a great rain in some form or another
As far as I know this as the same as the planet x theory, 12th planet, or nibiru"
Then two quotes down the page it says:
"I'm askin if you have heard of this specific theory, because its really not too far fetched
-If you read up on the specifics you will likely find a bunch of radical conspiracy theory bs
-im not worried about that i just wanna know if anyone believes this theory is possible
-all continents have stories of a great flood in their history and this could explain such things as the water damage on the great pyramids
hope that helps and i dunno y nobodys postin responses but a'ight"
