While I can show respect to your beliefs, you need to understand that there are thousands of religions out there. To say your religion is "the one" is the type of arrogance that gets this country in heat.
Here are some facts, believe what you want though:
The Catholic church has added more amendments to what they believe over the past 500-700 years, it's mind-blowing. As science progresses and proves without a doubt that things are BS, the church changes the story to fit the facts.
The bible is NOT the same print that it was 2,000 years ago. It was written in Aramaic, then Hebrew, then translated (faintly) into several languages. Then was edited by King James... THAT is what we read today.
So because of this, who is to say that it's fact, and not what King James wanted to be there? It was originally written in Aramaic, yet people today think that nothing could have been lost in translation from a language that has not been spoken in a few thousand years.
God flooded the Earth... Was it fresh water? That would kill all Ocean life. Was it Salt Water? That would kill all plant life on the earth, and not allow any to grow to this day. And where would it all go afterwards?
Bold one: Wrong religion.
Bold two: Because; You can literally go and translate it for yourself. Not from the "king James" version but the original text. You will need to know Hebrew, Aramaic, and Greek though =P
Bold three: If you say "okay maybe he did flood the world". Then don't you think that he could also remove all that water within a blink of an eye? Not to say he did, he prolonged the removal.
Whose to say that the water could not have been what is called "brackish". Where fresh water meets salt water. The water does not have to be all the same, it could have been salt in some areas and fresh in others.
