Do you really think dinosaurs were killed by a meteorite? Actually the aliens did it?

Question

Old Man Dirt · Accepted Answer

I am pretty sure it was not aliens.
What we know is that there was a major event or events that resulted in:
1. A major climate change.
2. A drop in oxygen levels.
It is unclear if it was a meteorite, a major volcanic  eruption, polar shift, major change in the earths orbit or all of the above.
I lean towards all of the above. Some event triggered caused enough vegetation to die off and be buried fast enough that it turned to coal/oil. It also generated enough fall out that many other dead things got buried fast enough they did not rot, but turned to fossils.
Aliens I just don't think could have generated that kind of dirt or rocks to form on top of the remains.

In Science we use what we KNOW about to theorize how things happen, before we move on to things we do not know about.---We know Meteorites exist and can do the job---We do NOT know anything about Aliens.  So we always favor the theory where we do not use unknown elements.

Tom S · Answer

Meteorites are way to small, it was either an asteroid or comet.

Asimov Was A Genius · Answer

They were not killed by a meteorite - meteors are tiny bits of debris that usually burn up in the atmosphere.
It was very likely a large asteroid, but if you want to believe aliens did it you go right ahead.

Many were not killed directly
The Asteroid was of the Baptistina family
From a former larger Asteroid called Baptistina that got broken up during the Last great Bomardment 3.8 Billion Years ago
 A twin if the Same Asteoid caused the Tcyhco Crater on the Moon
So we owe it one for Evolution sake
 The Asteroid in Question was the size of Los Angeles
About 9 Miles wide
The impact is now known to have taken place in the Gulf of Mexico
 The Crater was found through Echo Sounding by An Oil company, measuring 250 miles in Diameter
It was a Doozy
I wouldn't have wanted to be underneath it, unfortunately many Dinosaurs were to their detriment
 Many more creatures also perished in the Plasma it created, Schockwaves and Tsumamis
It became a Nuclear Winter for the whole Planet
The World was changing at that time anyway
Much upheaval with the Continents Moving
Earthquakes and Volcanoes, Global warming from high CO2, the days of the Dinosaurs were numbered and a Brave New World sprang up Ruled by Mammals
