What evidence (specifically) would be required for you to abandon your belief in YEC

I think there's a mistake in thinking that is the core question, and its one I made myself earlier in the thread but no-one picked up on it, so I didn't highlight it.   Here's the definition of YEC from Wiki, but something similar could be found elsewhere:

Young Earth creationism (YEC) is the religious belief that the Universe, Earth, and all life on Earth were created by direct acts of the Abrahamic God during a relatively short period, sometime between 5,700 and 10,000 years ago


Ok? So that's actually three statements combined

Young Earth creationism (YEC) is
i) the religious belief[1] that the Universe, Earth, and all life on Earth were created by direct acts of the Abrahamic God
ii) This took place during a relatively short period

iii) This was sometime between 5,700 and 10,000 years ago


So, without spelling it out too much, I asked pete and Iona what the evidence for (iii) was for non-believers, i.e. for those who did not accept (i).

Pete was, as before, quite honest and said he did not know of any. His approach was that (i) was true because it was revealed in the bible, and that lead him to (ii) and (iii). Any evidence to the contrary must therefore be misunderstood or flawed. Pete, feel free to contradict if I have misunderstood.


Iona, not surprisingly, missed the question and tried to give evidence for creationism, not for a young earth.


All of which leads back to why I don't think you are asking quite the right question. Which is, imo, "What is your measurable evidence that the earth is young?" You can find as many objections as you like against>/u> the evidence for an old earth, but that is not evidence for a young one.
