You do realize that the last ice age was due to a global extinction level event (impact from more than likely an asteroid or comet) not just a random fluctuation in the earths climate, right? Ya know that thing that killed off all the dinosaurs.
This isn't even remotely true. The last major "ice age" - the Pleistocene Epoch - occurred long, long, looooong after the dinosaurs were gone, and while it is certainly possible that a comet impact could cause an ice age, scientists generally agree that ice ages are caused by a complex relationship between things like ocean current, atmospheric composition, distance from the sun, intensity of solar radiation, etc.
I'm not even sure what point you were trying to make, but your statement was so utterly silly that you should probably just stop now.
