I think we need to ask Strat94 what he knows about it? Seeing as he is from Planet ETO but here is the final explanation. There is so much crap (literally) in space no telling when we will start finding all kinds of debris in our yards and streets.

By Wednesday evening, Dallas police were leaning toward a more terrestrial explanation. An investigator visited a nearby tree-mulching business and saw that the object closely resembled a tooth from one of the large mulching machines.
After looking at a photo of the object Wednesday, one expert said it did look as if it were from space.
"This thing was exposed to a tremendous amount of heat," said Max Corneau, vice president of the Texas Astronomical Society of Dallas and a senior Army space operations officer.
It's not unusual for space debris to make it to Earth's surface, he said. "What is fairly uncommon is that pieces actually go through people's houses."
But sometimes such unidentified flying objects have turned out to have more down-to-earth origins.
Just last week, an 8-pound chunk of metal that crashed through the roof of a warehouse in Jersey City, N.J., sparked theories that the object was satellite debris.
But police soon determined that the rectangular piece of metal had flown off a large mulching machine at a nearby business about three football fields away, according to media reports.
