So Creationist, you believe the earth is 6000 years old and that dinosaurs died in Noah's flood. Can you explain this?

Iridium is an element which is very rare in the Earth's crust but very abundant at the sites of meteorite impacts.
There is a worldwide layer of iridium located at the geological layer which is conventionally dated to about 65 million years ago, the time when dinosaurs disappear from the fossil record and when a massive asteroid impacted what is now the Yucatan peninsula.


So...if dinosaurs actually died in a a big flood, why do they all disappear at the same time when a massive impact event seems to have occurred?
How does a flood produce iridium?

Y'all don't have to answer, just take it into consideration when you're considering the true history of our planet and whether your interpretation of the Bible is coherent with the evidence.
