NOAH DID NOT PREACH! NOAH DID NOT HAVE FAITH! THIS IS A MYTH ON A MYTH!
(Genesis 6:17-18) 17
"And as for me, here I am bringing the deluge of waters upon the earth to bring to ruin all flesh in which the force of life is active from under the heavens. Everything that is in the earth will expire. 18 And I do establish my covenant with you; and you must go into the ark, you and your sons and your wife and your sons? wives with you.
No Freaking neighbors! There was no preaching nor attempt to save anyonw except noah. Thats like says lot preached to sodom. "God" just killed those people if the story is true. The reason is there was no organized religion concept he only took care of the people he knew personally. It was cronyism.
People talk about what the world would be with out religion. Um if you are not a paranoid schizophrenic with a temporal lobe disorder you are cannon fodder. At least according to the bible.
