What are the likely causes for the extinction of the dinosaurs?
There are numerous theories for this great extinction, but at present only three are taken seriously: 1. Fossil evidence shows that there was a gradual decline in the abundance and variety of dinosaurs during the last 10 million years of the Cretaceous Period. This may have been because the climate climate became much cooler and drier. 2. In India, huge volcanic eruptions unleashed enormous quantities of lava, volcanic ash and poisonous gas which would have caused widespread climatic change. 3. At about the same time a large asteroid struck the Earth forming a 240 kilometre crater in what is now the Yucatan Peninsula in Mexico. This impact would have caused – among other disasters – several extremely cold months or years because of dust in the atmosphere. Regarding Noah…The end of the Cretaceous period was around 65.5 million years ago but it was only around 50,000 years ago that homo sapiens started using stone tools. Unless he was a time traveller there wouldn’t have been any arks
There were probably a number of causes, some undoubtedly related to the meteorite that slammed into the earth at the end of the Cretaceous Period. If your friend wants to use the “flood” idea, he’d have to show all of the following: 1 – That such a flood took place. No scientist has successfully demonstrated that it must have happened. 2 – That this flood eliminated the dinosaurs. We should expect to see their fossils in all strata, not just in strata of certain death. That is not the case. 3 – That dinosaurs and people existed simultaneously. Again, all evidence suggests that this is not the case. I’m not talking about a possible remnant here and there; I’m talking about a time when dinosaurs were as common and as known as birds, fish, and bugs.
