Do you really think Earth survived 4.5 billion years without being hit by a supernova or a massive comet and being completely destroyed?

We don't live near any stars large enough to CAUSE a supernova, and earth HAS been hit by meteorites, and it still does, every DAY.
Supernovas are caused by stars and, apart from our sun (which WILL go supernova, one day), they're way too far away, and getting further every day. We HAVE been hit by comets, meteors, meteorites and asteroids, and we still are being hit daily. Fortunately, they're small and either burn up or do negligible damage. Space is a big place and we are pretty small. Comets, meteors, etc. are even smaller. Plenty of room to miss !
What Zim said.
Sol will possibly go nova, but it lacks the mass to go super.
The hypothetical "Giant Impact" that created the Moon was estimated to have occurred about 4.52Bya, so Yes.
Dino... the Sun hasn't gone supernova and won't for a long time yet. The dinosaurs, your namesake, were wiped out by a meteor or small asteroid striking just off shore from the Yucatan Peninsula. There have been other massive meteor strikes (Arizona, Siberia) so the Earth has not gone unscathed.

Per the Cracked.com article,

All hail the FSM! What meat balls he has.

I'm also Ji.
This planet is lucky not to have been hit with some black hole "expulsion jet" (or whatever you call it) that is essentially a "death ray".
So according to the Cracked article it is possible every day is Apocalypse day, but I doubt you are going to be zapped into a higher plane when if happens.
"apart from our sun (which WILL go supernova, one day)"
Not it wont its actually too small, it will expand into a red giant as part of its cycle.
I don't know about comets. We've been hit by asteroids for sure. And I would say that whatever caused the Chicxulub crater was pretty massive. But I'm not an astronomer and couldn't tell you what size an asteroid has to be in order to be considered 'massive'.
And yeah, I quite obviously believe that the earth has survived for 4.5 billion years without being completely destroyed because, guess what, I'm at my computer, typing this, on a 4.5 billion year old planet. If it hadn't survived 4.5 billion years, I wouldn't be here typing this.
That, and it's actually pretty hard to utterly destroy a planet. Destroying life on said planet, that's much easier. But just look at the number of mass extinctions this planet has had! It was the mass extinction at the end of the Cretaceous that allowed the rise of mammals -- including, eventually, the evolution of human beings.
Yes. it's still here isn't it?
See, this is why you shouldn't make claims that can be contradicted by all five senses of the person you're talking to.
Earth has been hit multiple times by comets and asteroids, and survived, and some scientists believe was hit once by a supernova (in the form of a gamma ray burst) that caused the Ordovician mass-extinction. Imagine what a bit of education will teach you...
Confused?
So were we! You can find all of this, and more, on Fundies Say the Darndest Things!
