This is only suspect to the type of person who in times long past would have believed that the sun rotated about the earth and that the earth was the center of the universe.
As was noted by many astronomers and hobbyists, the asteroid made an approach from the southern direction--whereas the meteorite made an east-west approach. There is no way they were part of the same event.
Please take a moment to be at one with the size of the universe, or to come as close to that as you are able. The size is immense and beyond anything you could possibly conceive in a tangible sense.
Even the size of our solar system is likely beyond the grasp of your mind (and all of our minds at that).
This is the LAST PLACE that you will ever get a surprise on the last day--there are far too many hobbyists out there for something like this to go un-noticed. The government would be hard pressed to lie about this.
There are so many scientists looking at this, even if a good swath of them are in cahoots--you wouldn't ever shut them all up.
Take a look at the following map of the solar system, note that there is an extremely expansive asteroid belt very near to us--and there is a second even larger belt on the outskirts of the solar system (called the Kuiper belt--pronounced Kigh-Purr).
Belt doesn't really do them justice--they are more like asteroid spheres.
Now if we have that many space rocks zooming around this close to home, imagine how many more there are in the universe.
This might seem like a rare event, or an unlikely coincidence--but the reality is that in a universe our size, there is almost nothing which fits that description.
