Dave there are a lot of people who hold to this very idea. In fact some researchers have gone out to disprove the bible they have actually showed how it is possible by nature itself. They can prove scientifically all 10 plagues etc etc. While I think that may be fine and dandy for them. I accept by faith it was as it was written in scripture. If God used natural causes well that is even better. Do not stop posting. Some of this stuff is very intriguing. Just be ready to defend or preface it (as you did here) as a simple what if. Not sure why NateR went off like that. You would have thought you were Buzzard there will all that malice. Maybe he is having a bad day.
