The problem with the YEC View of the world, and especially with your view, is that you think one exception conclusively dismantled evolution.
It's the larger pattern of evidence, and the convergence of multiple lines of evidence, which conclusively corroborates the following:
The YECs have no explanation for the 100,000+ years of uninterrupted annual weather patterns.
The YECs have no explanation for millions of years of mammalian differentiation above the K-T boundary, vs the even more robust millions of years of reptilian differentiation below the K-T barrier;
The YECs don't even have an explanation for how there could be a K-T boundary in a flood scenario;
o Nor why there should be reptile foot prints in the middle layers of flood sediments;
o Nor why there should be no flowering plants (which can't swim) in the primitive plant levels;
o Nor why there are blooming plants and even rain drop patterns in the middle of these alleged flood sediments.
'4.' The YECs don't have an explanation for how marsupials gained an ecological monopoly in Australia... if both placental and marsupial mammals were released from the Ark at the same time.
'5.' And finally, there are YECs who fail to reconcile how there can be a phase of animal hyper- speciation immediately after the Ark is opened.... all the while speciation is considered "impossible".
