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?
