So I watched part of "Day Two" ... didn't have time to watch more than like 10-15 minutes in, but the theory they're floating (and it is just a theory) is that in the beginning the earth was in the middle of a giant (6 billion-mile diameter) ice ball. Not sure where they got this number from. Then the "light" of the First Day, "Let there be light." was some kind of giant sun they picture off to the right that was big enough to melt the ice into water. I hope they realize that this theory will be considered just as ridiculous (if not moreso) than Flat Earth by the scientific mainstream whose favor they're attempting to curry.
So, after Day One, when the ice was now melted into water, God created a firmament in the middle of the now giant ball of water, to separate the water from the earth. Interestingly, they cite numerous Church Fathers indicating that the firmament was solid, but then promote a theory that somehow the firmament "changed" on "Day Four" when God put the sun, moon, and stars in it, expanding massively and therefore becoming at that time a more ethereal substance, having been "stretched out", i.e. transforming into what we now know as space. Dr. Sungenis admits that Scripture is silent on the matter, but then claims there are hints about it there ... none of which I really buy. I'm interested to hear, then, with this theory, how during the time of the Great Flood, Sacred Scripture indicates that the windows of the firmament were opened to create some of the flood waters. Perhaps some huge blast of water flew in from the edge of space and clobbered the earth.
Now, Dr. Sungenis does cite some physicist who discussed the idea that the universe could be much smaller than is generally claimed.
But the one thing I notice throughout is that Dr. Sugenis begs the question that "outer space", as described by modern "science" actually exists as such, with the possible exception of it perhaps being smaller than is generally believed. He said that the original solid firmament had to be stretched out because it was "too small" to hold the sun, moon, stars, etc. This simply begs the question that the sun and stars are the size and distance from earth that modern science claim they are.
If you look at this picture again, what's to prevent the Flat Earth "snow globe" model of the earth from being in the center there? Nothing other than Sungenis' acceptance of the claim of modern science.
I do respect the fact that Dr. Sungenis and Hugh Owen take Sacred Scripture literally and are attempting to come up with an explanation for it in its literal sense, but I disrespect the fact that 1) they lump FEs in with all those who deny the historicity and inerrancy of Sacred Scripture and 2) dismiss FE on the basis of modern "science", often ridiculing and disparaging it ... despite the fact that modern science would ridicule his giant ice/water ball theory perhaps even more than Flat Earth.
