Your technical ineptitude may actually help you to stumble onto the truth in spite of your bias. By your own analysis, your 10,000 ft. allowance may not be too far off the mark. Do you really think all those mountain ranges would have been and remained at approximately their present heights with all that seismic activity you properly discerned resulting from the flood? Since you're on a technical roll refresh my memory. Where do plankton and algae live? On another point, since you mentioned glaciers, do you fancy them floating around somehow problematic, and do you think Earth can't survive changing ocean currents and atmospheric patterns? Perhaps moron those topics could be clarified for the class.
Your technical ineptitude may actually help you to stumble onto the truth in spite of your bias. Do you really think a flood would have more of an effect on mountain ranges rooted in the mantle or on fragile canyons? While your on a technical roll, what effect would half a mile of limestone solidifying (a thermogenic event) have on the temperature of the earth? Finally, what effect does internet banter have on the lack of evidence for a global flood and the positive evidence for there never being one?
Put your poor, injured but massive, ego down for one second and reason it out.
