Killer space rocks is a better bet. there is at least some proof of them hitting the earth. Got a few friends in DARPA/NASA biz and they agree with this guy. We have only spotted 15% of the rocks that might be headed our way. Lots of times we have near misses that we find out afterward or only a few days ahead.

That recent hit on Jupiter took everyone by surprise. Any of the asteroids in Langrangian points in Jupiter's orbit could easily be knocked out of sync and wipe us all out. I would think that cataloging near Earth objects should be a prerequisite for and one of NASA's top priorities. Going to the moon is nice but what's the point if there's nothing to come back to. The odds are small yes, but we've seen more than one collision in these recent years.

All you have to do is look at the Moon to see how much crap has collided with us. It’s only a matter of time. I just hope it’s not in my time.

“there is at least some proof of them hitting the earth.”

Some? There is lots and lots of very large impacts, leaving craters 10s of miles in diameter - there’s even one in France I believe.

There a big round hole blasted into the ocean floor off the Yukatan coast... seems it was made around 65 MYA...

The astroids we have least knowledge of or time to react to come from behind the sun. The 15% figure is an estimate based on a guess about the total number. The actual number is likely much higher.

Then there are comets which we’ve seen hit Jupiter and cause numerous big holes.
