Most of your replies fall under the category of the logical fallacy of "mere assertion."
Eg - you have "evidence" to back your dates up (where?), all I have is "ancient mythology" (just calling it "mythology" doesn't make it that), "there isn't a reliable genealogy in the Bible" (again, just saying it isn't reliable doesn't make that true), "the Bhagavad Gita and Rainbow Serpent myths are as valid as the Bible" (oh really? thanks for sharing your opinion), "seems to me you are using circular arguments" (you haven't identified which argument I made that was circular), and "not in a position to comment on someone who has actually studied the Bible" (why not? are you implying you've studied it more than I have? what is it about my comment that makes you think I'm not in a position to comment, please?)
Since those are just mere assertions and you haven't shared a reason to believe them, I don't need to answer them further.
Correcting your statement by saying you meant to say "modern YEC" doesn't fix the problem. Since you know about Ussher (not to mention all the other scholars and theologians that would come down on the side a recent age for the earth throughout history) it's not reasonable to just assume that those in the modern YEC movement don't have access to that information as well. They may have got it from him, or other scholars, instead of Ellen White. If you don't know the place they got it from, then that in itself is another form of "mere assertion." You don't know.
As for your reply to my highlighting the problem about unverifiable assumptions about initial starting conditions in dating mechanisms, you didn't respond to that issue at all. You merely said "False" (another mere assertion on your part), and then proceeded to answer me as if I had said only 1 radiometric dating method establishes an older age than what the Bible confirms. That's not what I said. I was talking about the assumptions regarding initial conditions. If that information is unknown in all radio-metric dating methods (which it is, because we weren't there to measure it, and there's no way to measure a sample from the past), then that goes across all radio-metric dating methods, and the number of how many there are doesn't matter.
Merely stating your position is not an argument for that position. If you have a reasons to believe the assertions you're making, or reasons why I should believe them too, please let me know what those reasons are.
