We don't know Squat about the Dino's, its just a theoretical fact based on Carbon Dating.
Religion: Relgion on religious terms was never invented, Religion created and was meant to be followed.
People use it as an excuse.
Example:, Ireland: The IRA and UK (North Ireland) Province/State have been fighting for years, and they fight each against each other as Catholics and Protestants. They're all people, they only fight each other not because the other is different, only because there parents have done so.
Point: Radical Idiots that don't actually believe in what the religion teaches (Just like what I mentioned above, you can't kill in a Religion that demands peace and BLAME it over the fact that someone doesn't follow your religion). Religion has been made as something to blame on, if you really could think pass through it and look at the REAL reasons. (On a different note: Defending your self when someone attacks you because of your religion is basically the same thing, they hate you because your different. Meeh.)
So religion doesn't work.
Dino's don't work.
Bacteria could mean Plagues, spreading of diseases.
And, besides that, Leaders killing people (Stalin, Hitler), or monstrous wars themselves. Even though there were other Genocide killings/killings for some other reasons, these resulted in the most death.
Or BCE times, some very old kingdoms show historical signs of mass killings, who knows.
It doesn't really matter, since not all of these events should be horrid enough to be given the honour of beings Earth's worse. After all, Earth is a very lively planet, everything can happen, so lets all be awesome and lets hope that we can PREVENT this crazy future disastur.
