What presuppositions? Are you saying that geologists who have studied the results of other floods would be incapable of detecting the Deluge by extrapolating from what they know of other floods?
Are you saying geneticists who have clocked the rates of change within different genomes cannot use those rates to determine how long it's been since a particular species descended from a genetic bottleneck, such as what happened to the cheetah 10k years ago, or humanity ~70k years ago (when our species was reduced to a couple of thousand individuals) -- and using that to determine that some organisms have never undergone such bottlenecks, while others have at wildly different periods throughout the history of the planet? Are you saying researchers who use calibrated radioactive decay rates for everything from timekeeping to medicine to food preparation are making "unfounded assumptions" when they use that same data to determine when a rock first solidified, or the organism last took in carbon-14?
Are you saying that researchers who have bored through old trees or into glaciers or into ancient lake beds, counted the rings and layers, and calibrated those annual markers with data derived from radiometric dating (which just happens to match up with the tree rings and glacier layers and lakebed varves -- go figure), are making "unfounded assumptions" even though they double checked their findings against other dating methods?
Bubba, if science was based on "unfounded assumptions" it couldn't make consistent findings upon which modern technology is based.
Nope. The only "unfounded assumptions" being made are by the anti-Es who want to toss out any research that does not correspond to their preconceived notions.
First of all you must understand this, that scoffers will come in the last days with scoffing, following their own passions and saying, "Where is the promise of his coming? For ever since the fathers fell asleep, all things have continued as they were from the beginning of creation." They deliberately ignore this fact, that by the word of God heavens existed long ago, and an earth formed out of water and by means of water, through which the world that then existed was deluged with water and perished.But by the same word the heavens and earth that now exist have been stored up for fire, being kept until the day of judgment and destruction of ungodly men. But do not ignore this one fact, beloved, that with the Lord one day is as a thousand years, and a thousand years as one day. The Lord is not slow about his promise as some count slowness, but is forbearing toward you, not wishing that any should perish, but that all should reach repentance. But the day of the Lord will come like a thief, and then the heavens will pass away with a loud noise, and the elements will be dissolved with fire, and the earth and the works that are upon it will be burned up. Since all these things are thus to be dissolved, what sort of persons ought you to be in lives of holiness and godliness, waiting for and hastening the coming of the day of God, because of which the heavens will be kindled and dissolved, and the elements will melt with fire! But according to his promise we wait for new heavens and a new earth in which righteousness dwells. Therefore, beloved, since you wait for these, be zealous to be found by him without spot or blemish, and at peace. (2 Peter 3:3-13)
Notice that St. Peter uses the flood as the context in which to identify the scoffers in the last days. St. Peter mentions the flood and Noah three times in his two epistles. He treats it as a real event. So either he was right or he was a false prophet.
Think about that before you scoff at those who accept the flood as a fact. We are numbered with St. Peter. Are you?
Wow! Show me those 70K year old trees! How exciting. And the "ancient ice" drilling research in Antarctica only goes back a few thousand years, or so I had previously thought. Have they drilled into a 70K old glacier in the arctic that I haven't heard about?
What a job--counting 70K rings on that stump.
