Ummm... no. Over time Jupiter and Saturn's gravity knock asteroids which are happily orbiting in the asteroid belt into earth-crossing orbits.
So because we haven't had a planet killer asteroid impact in 300,000 years means that we're in the clear? I'll have to take that logic to the craps table next time I'm in Vegas. "Well, haven't seen a 7 in 5 rolls, they must not exist!".
And besides "earth killer" impacts, we are susceptable to impacts which can cause "serious regional damage" about once per century. I for one am glad that some rational people are "obsessing" over it.
