When, according to bible believers, did the Chicxulub asteroid strike the Earth?

This is the asteroid that hit somewhere in what is now Mexico that would have destroyed 90% of life on the planet. If it came after the 6th day of creation, humans would have probably not survived. If it happened before, like say the 4th day of creation, humans still would not have survived since the affects lasted well past that. So did the asteroid never actually hit but god just planted it there on the first day or whatever, just for fun?
