This is an artificial time demarcation created by those who believe the earth is very old. And most evidence indicates that it is not very old. So I guess that makes the answer 'yes' and 'no.' |
Well, if you accept the evidence for the K/T impact event, you must be fairly confident that the evidence for other impact events as collated by the Earth Impact Database folks is reasonably reliable? From their estimates of the terrestrial cratering rate, they reckon a K/T event occurs once every 50-100 million years. From your perspective, this rate is obviously nonsense as the Earth is less than 10,000 years old. However, if the cratering rate is based on a count of actual, observed events, then in and of itself it must be an absolute and can be applied to whatever timespan we believe the Earth to have existed? My simple sense of math leads me to make this uncomplicated comparison:
'Deep Time' age of Earth: c.4.5byo (rounded for simplicity)
'YEC' age of Earth: c.10kyo (upper limit used)
Rate of K/T impacts ('Deep Time'): every 50-100my
Probable no. of K/T impacts ('Deep Time' - lower rate used): 45
Probable no. of K/T impacts applied to 'YEC' dating: 1 every 222 years
I am sure you can kick all sorts of holes in this logic (I can myself), but as the EID lists a total of seven impact events with diameters >50% that of the K/T event and no fewer than 41 with diameters of at least 20km (reckoned to produce atmospheric blow-out and nuclear winter effects)
the K/T monsters that have been identified occurred every 1,430 years under the 'YEC' model or, if you really think they are all post-flud, even more frequently (every 720 years). Make the same back-of-an-envelope calculations for those of 20kms or greater and its every 250 years (10,000 years) or every 125 years (post-flud). Or did they all occur within a few short weeks/months/years of the flud? If they did, how come nobody noticed?
