where in the hell do you come up with that size for elephants "back then". which brings up another point. when was "back then"? you know, the "back then" when noah supposedly did his thing? "back then" when the universe was created? best i can figure from my former bible studies, yes i was a presbyterian for the first sixteen years of my life, the god fearing think that "back then" was about six thousand years ago. hell the wooly mamoth, from which we think the elephant descended from, dwarfed the present day elephant. are you saying elephants shrunk for a spell "back then"? and saying that a day was longer "back then" as the faithful so often do, simply will not do. precisely how long was a day "back then"? i know what science say's a day looked like "back then" six thousand years ago. the bible states numbers of years that folks like noah lived, hundreds if i'm not mistaken, and numbers of days that god created the universe. but since you want to use science, what is the measure, the weight if you will, the duration of days, weeks and years "back then"? hmmmmmm?
you're right. we have to use science even when it isn't convenient. so go ahead. use science to support this "hypothoses" called noah's ark.
oh yeah, nearly forgot. astrophysicists are split on whether the universe is expanding or retracting.
